The North Atlantic Treaty Organization called the North Atlantic Alliance, is an intergovernmental military alliance between 29 North American and European countries. The organization implements the North Atlantic Treaty, signed on 4 April 1949. NATO constitutes a system of collective defence whereby its independent member states agree to mutual defence in response to an attack by any external party. NATO's Headquarters are located in Haren, Belgium, while the headquarters of Allied Command Operations is near Mons, Belgium. Since its founding, the admission of new member states has increased the alliance from the original 12 countries to 29; the most recent member state to be added to NATO is Montenegro on 5 June 2017. NATO recognizes Bosnia and Herzegovina, North Macedonia and Ukraine as aspiring members. An additional 21 countries participate in NATO's Partnership for Peace program, with 15 other countries involved in institutionalized dialogue programs; the combined military spending of all NATO members constitutes over 70% of the global total.
Members have committed to reach or maintain defense spending of at least 2% of GDP by 2024. On 4 March 1947 the Treaty of Dunkirk was signed by France and the United Kingdom as a Treaty of Alliance and Mutual Assistance in the event of a possible attack by Germany or the Soviet Union in the aftermath of World War II. In 1948, this alliance was expanded to include the Benelux countries, in the form of the Western Union referred to as the Brussels Treaty Organization, established by the Treaty of Brussels. Talks for a new military alliance which could include North America resulted in the signature of the North Atlantic Treaty on 4 April 1949 by the member states of the Western Union plus the United States, Portugal, Norway and Iceland; the North Atlantic Treaty was dormant until the Korean War initiated the establishment of NATO to implement it, by means of an integrated military structure: This included the formation of Supreme Headquarters Allied Powers Europe in 1951, which adopted the Western Union's military structures and plans.
In 1952 the post of Secretary General of NATO was established as the organization's chief civilian. That year saw the first major NATO maritime exercises, Exercise Mainbrace and the accession of Greece and Turkey to the organization. Following the London and Paris Conferences, West Germany was permitted to rearm militarily, as they joined NATO in May 1955, in turn a major factor in the creation of the Soviet-dominated Warsaw Pact, delineating the two opposing sides of the Cold War. Doubts over the strength of the relationship between the European states and the United States ebbed and flowed, along with doubts over the credibility of the NATO defense against a prospective Soviet invasion – doubts that led to the development of the independent French nuclear deterrent and the withdrawal of France from NATO's military structure in 1966. In 1982 the newly democratic Spain joined the alliance; the collapse of the Warsaw Pact in 1989–1991 removed the de facto main adversary of NATO and caused a strategic re-evaluation of NATO's purpose, nature and focus on the continent of Europe.
This shift started with the 1990 signing in Paris of the Treaty on Conventional Armed Forces in Europe between NATO and the Soviet Union, which mandated specific military reductions across the continent that continued after the dissolution of the Soviet Union in December 1991. At that time, European countries accounted for 34 percent of NATO's military spending. NATO began a gradual expansion to include newly autonomous Central and Eastern European nations, extended its activities into political and humanitarian situations that had not been NATO concerns. After the fall of the Berlin Wall in Germany in 1989, the organization conducted its first military interventions in Bosnia from 1992 to 1995 and Yugoslavia in 1999 during the breakup of Yugoslavia. Politically, the organization sought better relations with former Warsaw Pact countries, most of which joined the alliance in 1999 and 2004. Article 5 of the North Atlantic treaty, requiring member states to come to the aid of any member state subject to an armed attack, was invoked for the first and only time after the September 11 attacks, after which troops were deployed to Afghanistan under the NATO-led ISAF.
The organization has operated a range of additional roles since including sending trainers to Iraq, assisting in counter-piracy operations and in 2011 enforcing a no-fly zone over Libya in accordance with UN Security Council Resolution 1973. The less potent Article 4, which invokes consultation among NATO members, has been invoked five times following incidents in the Iraq War, Syrian Civil War, annexation of Crimea; the first post-Cold War expansion of NATO came with German reunification on 3 October 1990, when the former East Germany became part of the Federal Republic of Germany and the alliance. As part of post-Cold War restructuring, NATO's military structure was cut back and reorganized, with new forces such as the Headquarters Allied Command Europe Rapid Reaction Corps established; the changes brought about by the collapse of the Soviet Union on the military balance in Europe were recognized in the Adapted Conventional Armed Forces in Europe Treaty, signed in 1999. The policies of French President Nicolas Sarkozy resulted in a major reform of France's military position, culminating with the return to full membership on 4 April 2009, which included France rejoining the NATO Military Command Structure, while maintaining an independent nuclear deterrent.
Between 1994 and 1997, wider forums for regional co
Grumman S-2 Tracker
The Grumman S-2 Tracker was the first purpose-built, single airframe anti-submarine warfare aircraft to enter service with the United States Navy. Designed and built by Grumman, the Tracker was of conventional design — propeller-driven with twin radial engines, a high wing that could be folded for storage on aircraft carriers, tricycle undercarriage; the type was exported to a number of navies around the world. Introduced in 1952, the Tracker and its E-1 Tracer derivative saw service in the U. S. Navy until the mid-1970s, its C-1 Trader derivative until the mid-1980s, with a few aircraft remaining in service with other air arms into the 21st century. Argentina and Brazil are the last countries to still use the Tracker; the Tracker was intended as a replacement for the Grumman AF Guardian, the first purpose-built aircraft system for ASW, using two airframes for two versions, one with the detection gear, the other with the weapon systems. The Tracker combined both functions in one aircraft. Grumman's design was for a large high-wing monoplane with twin Wright Cyclone R-1820 nine cylinder radial engines, a yoke type arrestor hook and a crew of four.
Both the two prototypes XS2F-1 and 15 production aircraft, S2F-1 were ordered at the same time, on 30 June 1950. The first flight was conducted on 4 December 1952, production aircraft entered service with VS-26, in February 1954. Follow-on versions included the WF Tracer and TF Trader, which became the Grumman E-1 Tracer and Grumman C-1 Trader in the tri-service designation standardization of 1962; the S-2 carried the nickname "Stoof" throughout its military career. Grumman produced 1,185 Trackers. At least 99 and 100 aircraft carrying the CS2F designation were manufactured in Canada under license by de Havilland Canada. U. S.-built versions of the Tracker were sold to various nations, including Australia, Japan and Taiwan. The Tracker carried an internal torpedo bay capable of carrying two lightweight torpedoes or one nuclear depth charge. There were six underwing hard points for rocket pods and conventional depth charges or up to four additional torpedoes. A ventrally-mounted retractable radome for AN/APS-38 radar and a Magnetic Anomaly Detector AN/ASQ-8 mounted on an extendable rear mounted boom were fitted.
Early model Trackers had an Electronic Surveillance Measures pod mounted dorsally just aft of the front seat overhead hatches and were fitted with a smoke particle detector or "sniffer". S-2s had the sniffer removed and had the ESM antennae moved to four rounded extensions on the wingtips. A 70-million-candlepower searchlight was mounted on the starboard wing; the engine nacelles carried JEZEBEL sonobuoys in the rear. Early Trackers carried 60 explosive charges, dispensed ventrally from the rear of the fuselage and used for active sonar with the AN/AQA-3 and AQA-4 detection sets, whereas the introduction of active sonobuoys and AN/AQA-7 with the S-2G conversion saw these removed. Smoke dispensers were mounted on the port ventral surface of the nacelles in groups of three each; the Tracker was superseded in U. S. military service by the Lockheed S-3 Viking. The last Navy S-2 was withdrawn from service on 29 August 1976. For many years the TS-2A version of the Tracker was used by U. S. Navy training units, culminating with its use by Training Squadron 28 for Student Naval Aviator training in the multi-engine pipeline with Training Air Wing FOUR at Naval Air Station Corpus Christi, Texas.
A number of Trackers live on as firefighting aircraft while the design continued to provide excellent service with the naval forces of other countries for years after the U. S. retired them. For example, the Royal Australian Navy continued to use Trackers as front line ASW assets until the mid-1980s; the Argentine Naval Aviation received seven S-2As in 1962, six S-2Es in 1978 and three S-2Gs in the 1990s. They were used from both aircraft carriers, ARA Independencia and ARA Veinticinco de Mayo and used in the COD, Maritime Patrol and ASW roles, they were extensively used in the 1982 Falklands War, first from Veinticinco de Mayo, from where they detected the British Task Force and from the mainland when the carrier returned to port after the sinking of the cruiser ARA General Belgrano. In the 1990s, six remaining airframes were refurbished by Israel Aerospace Industries with turboprop engines as S-2T Turbo Trackers; as of 2010, with the retirement of Argentina's only aircraft carrier, the Trackers are annually deployed on board Brazilian Navy aircraft carrier São Paulo during joint exercises ARAEX and TEMPEREX. and with U.
S. Navy aircraft carriers during Gringo-Gaucho maneuvers. Between 1967 and 1984 the Royal Australian Navy operated two Squadrons of S-2E and S-2G variants, based at NAS Nowra; these aircraft served with the RAN's 816 Squadron, which embarked aboard the Majestic-class aircraft carrier HMAS Melbourne as part of the 21st Carrier Air Group whenever that ship was deployed. During 17 years of operation of the Tracker, the RAN lost only one S-2 during aircraft operations due to an accident at sea on 10 February 1975. However, on 4 December 1976, a deliberately lit fire in a hangar at Nowra destroyed or badly damaged a large proportion of the RAN's complement of Trackers; these were subsequently replaced with ex-USN aircraft. The replacement aircraft were all S-2Gs, including the original aircraft modified by the US
Prince Edward Island
Prince Edward Island is a province of Canada consisting of the Atlantic island of the same name along with several much smaller islands nearby. PEI is one of the three Maritime Provinces, it is the smallest province of Canada in both land area and population, but it is the most densely populated. Part of the traditional lands of the Mi'kmaq, it became a British colony in the 1700s and was federated into Canada as a province in 1873, its capital is Charlottetown. According to the 2016 census, the province of PEI has 142,907 residents; the backbone of the economy is farming. The island has several informal names: "Garden of the Gulf", referring to the pastoral scenery and lush agricultural lands throughout the province. PEI is one of Canada's older settlements and demographically still reflects older immigration to the country, with Scottish, Irish and French surnames being dominant to this day. PEI is located about 200 kilometres north of Halifax, Nova Scotia, 600 kilometres east of Quebec City.
It consists of 231 minor islands. Altogether, the entire province has a land area of 5,686.03 km2. The main island is 5,620 km2 in size larger than the U. S. state of Delaware. It is the 104th-largest island in Canada's 23rd-largest island. In 1798, the British named the island colony for Prince Edward, Duke of Kent and Strathearn, the fourth son of King George III and the father of Queen Victoria. Prince Edward has been called "Father of the Canadian Crown"; the following island landmarks are named after the Duke of Kent: Prince Edward Battery, Victoria Park, Charlottetown Kent College, Charlottetown Kent Street, Charlottetown West Kent Elementary School Kent Street, GeorgetownIn French, the island is today called Île-du-Prince-Édouard, but its former French name, as part of Acadia, was Île Saint-Jean. The island is known in Scottish Gaelic as Eilean a' Phrionnsa or Eilean Eòin for some Gaelic speakers in Nova Scotia though not on PEI; the island is known in the Mi'kmaq language as Abegweit or Epekwitk translated as "land cradled in the waves".
Prince Edward Island is located in the Gulf of St. Lawrence, west of Cape Breton Island, north of the Nova Scotia peninsula, east of New Brunswick, its southern shore bounds the Northumberland Strait. The island has two urban areas; the larger surrounds Charlottetown Harbour, situated centrally on the island's southern shore, consists of the capital city Charlottetown, suburban towns Cornwall and Stratford and a developing urban fringe. A much smaller urban area surrounds Summerside Harbour, situated on the southern shore 40 km west of Charlottetown Harbour, consists of the city of Summerside; as with all natural harbours on the island and Summerside harbours are created by rias. The island's landscape is pastoral. Rolling hills, reddish white sand beaches, ocean coves and the famous red soil have given Prince Edward Island a reputation as a province of outstanding natural beauty; the provincial government has enacted laws to preserve the landscape through regulation, although there is a lack of consistent enforcement, an absence of province-wide zoning and land-use planning.
Under the Planning Act of the province, municipalities have the option to assume responsibility for land-use planning through the development and adoption of official plans and land use bylaws. Thirty-one municipalities have taken responsibility for planning. In areas where municipalities have not assumed responsibility for planning, the Province remains responsible for development control; the island's lush landscape has a strong bearing on its culture. The author Lucy Maud Montgomery drew inspiration from the land during the late Victorian Era for the setting of her classic novel Anne of Green Gables. Today, many of the same qualities that Montgomery and others found in the island are enjoyed by tourists who visit year-round, they enjoy a variety of leisure activities, including beaches, various golf courses, eco-tourism adventures, touring the countryside, enjoying cultural events in local communities around the island. The smaller, rural communities as well as the towns and villages throughout the province, retain a slower-paced, old-world flavour.
Prince Edward Island has become popular as a tourist destination for relaxation. The economy of most rural communities on the island is based on small-scale agriculture. Industrial farming has increased as businesses consolidate older farm properties; the coastline has a combination of long beaches, red sandstone cliffs, salt water marshes, numerous bays and harbours. The beaches and sandstone cliffs consist of sedimentary rock and other material with a high iron concentration, which oxidises upon exposure to the air; the geological properties of a white silica sand found at Basin Head are unique in the province. Large dune fields on the north shore can be found on barrier islands at the entrances to various bays and harbours
A sailor, mariner, or seafarer is a person who works aboard a watercraft as part of its crew, may work in any one in a number of different fields that are related to the operation and maintenance of a ship. The profession of the sailor is old, the term sailor has its etymological roots in a time when sailing ships were the main mode of transport at sea, but it now refers to the personnel of all watercraft regardless of the mode of transport, encompasses people who operate ships professionally or recreationally, be it for a military navy or civilian merchant navy. In a navy, there may be further distinctions: sailor may refer to any member of the navy if they are based on land. Seafarers hold a variety of professions and ranks, each of which carries unique responsibilities which are integral to the successful operation of an ocean-going vessel. A ship's crew can be divided into four main categories: the deck department, the engineering department, the steward's department, others. Officer positions in the deck department include but are not limited to: master and his chief and third officers.
The official classifications for unlicensed members of the deck department are able seaman and ordinary seaman. With some variation, the chief mate is most charged with the duties of cargo mate. Second Mates are charged with being the medical officer in case of medical emergency. All three mates each do four-hour afternoon shifts on the bridge, when underway at sea. A common deck crew for a ship includes: Captain / Master Chief Officer / Chief Mate Second Officer / Second Mate Third Officer / Third Mate Boatswain Able seamen Ordinary seamen Deck Cadet / unlicensed Trainee navigator / Midshipman A ship's engineering department consists of the members of a ship's crew that operates and maintains the propulsion and other systems on board the vessel. Marine engineering staff deal with the "hotel" facilities on board, notably the sewage, air conditioning and water systems. Engineering staff manage bulk fuel transfers, from a fuel-supply barge in port; when underway at sea, the second and third engineers will be occupied with oil transfers from storage tanks, to active working tanks.
Cleaning of oil purifiers is another regular task. Engineering staff are required to have training in firefighting and first aid. Additional duties include performing other nautical tasks. Engineers play a key role in cargo loading/discharging gear and safety systems, though the specific cargo discharge function remains the responsibility of deck officers and deck workers. A common engineering crew for a ship includes: Chief Engineer Second Engineer / First Assistant Engineer Third Engineer / Second Assistant Engineer Fourth Engineer / Third Assistant Engineer Motorman Oiler Entry-level rating Wiper Engine Cadet / unlicensed Trainee engineerUSA ships carry a qualified member of the engine department. Other possible positions include motorman, electrician, refrigeration engineer and tankerman. A typical steward's department for a cargo ship is a chief steward, a chief cook and a steward's assistant. All three positions are filled by unlicensed personnel; the chief steward directs and assigns personnel performing such functions as preparing and serving meals.
The chief steward plans menus. The steward may purchase stores and equipment. Galley roles may include baking. A chief steward's duties may overlap with those of the steward's assistant, the chief cook, other Steward's department crewmembers. A person has to have a Merchant Mariner's Document issued by the United States Coast Guard in the United States Merchant Marine in order to serve as a chief steward. All chief cooks who sail internationally are documented by their respective countries because of international conventions and agreements; the only time that steward department staff are charged with duties outside the steward department, is during the execution of the fire and boat drill. Various types of staff officer positions may exist on board a ship, including junior assistant purser, senior assistant purser, chief purser, medical doctor, professional nurse, marine physician assistant and hospital corpsman; these jobs are considered administrative positions and are therefore regulated by Certificates of Registry issued by the United States Coast Guard.
Pilots are merchant marine officers and are licensed by the Coast Guard. Mariners spend extended periods at sea. Most deep-sea mariners are hired for one or more voyages. There is no job security after that; the length of time between voyages varies by personal preference. The rate of unionization for these workers in the United States is about 36 percent, much higher than the average for all occupations. Merchant marine officers and seamen, both veterans and beginners, are hired for voyages through union hiring halls or directly by shipping companies. Hiring halls fill jobs by the length of time the person has been registered at the hall and by their union seniority. Hiring halls are found in major seaports. At sea, on larger vessels members of the deck department stand watch for 4 hours and are off for 8 hours, 7 days a week. Mariners work in all weather
The Avro Lancaster is a British four-engined Second World War heavy bomber. It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force during the same wartime era; the Lancaster has its origins in the twin-engine Avro Manchester, developed during the late 1930s in response to the Air Ministry Specification P.13/36 for a capable medium bomber for "world-wide use". Developed as an evolution of the Manchester, the Lancaster was designed by Roy Chadwick and powered by four Rolls-Royce Merlins and in one version, Bristol Hercules engines, it first saw service with RAF Bomber Command in 1942 and as the strategic bombing offensive over Europe gathered momentum, it was the main aircraft for the night-time bombing campaigns that followed. As increasing numbers of the type were produced, it became the principal heavy bomber used by the RAF, the RCAF and squadrons from other Commonwealth and European countries serving within the RAF, overshadowing contemporaries such as the Halifax and Stirling.
A long, unobstructed bomb bay meant that the Lancaster could take the largest bombs used by the RAF, including the 4,000 lb, 8,000 lb and 12,000 lb blockbusters, loads supplemented with smaller bombs or incendiaries. The "Lanc", as it was known colloquially, became one of the most used of the Second World War night bombers, "delivering 608,612 long tons of bombs in 156,000 sorties"; the versatility of the Lancaster was such that it was chosen to equip 617 Squadron and was modified to carry the Upkeep "Bouncing bomb" designed by Barnes Wallis for Operation Chastise, the attack on German Ruhr valley dams. Although the Lancaster was a night bomber, it excelled in many other roles, including daylight precision bombing, for which some Lancasters were adapted to carry the 12,000 lb Tallboy and the 22,000 lb Grand Slam earthquake bombs; this was the largest payload of any bomber in the war. In 1943, a Lancaster was converted to become an engine test bed for the Metropolitan-Vickers F.2 turbojet. Lancasters were used to test other engines, including the Armstrong Siddeley Mamba and Rolls-Royce Dart turboprops and the Avro Canada Orenda and STAL Dovern turbojets.
Postwar, the Lancaster was supplanted as the main strategic bomber of the RAF by the Avro Lincoln, a larger version of the Lancaster. The Lancaster took on the role of long range anti-submarine patrol aircraft and air-sea rescue, it was used for photo-reconnaissance and aerial mapping, as a flying tanker for aerial refuelling and as the Avro Lancastrian, a long-range, high-speed, transatlantic passenger and postal delivery airliner. In March 1946, a Lancastrian of BSAA flew the first scheduled flight from the new London Heathrow Airport. In the 1930s, the Royal Air Force was interested in twin-engine bombers; these designs put limited demands on engine production and maintenance, both of which were stretched with the introduction of so many new types into service. Power limitations were so serious that the British invested in the development of huge engines in the 2,000 horsepower class in order to improve performance. During the late 1930s, none of these was ready for production. Both the United States and the Soviet Union were pursuing the development of bombers powered by arrangements of four smaller engines, the results of these projects proved to possess favourable characteristics such as excellent range and fair lifting capacity.
Accordingly, in 1936, the RAF decided to investigate the feasibility of the four-engined bomber. The origins of the Lancaster stem from a twin-engined bomber design, submitted in response to Specification P.13/36, formulated and released by the British Air Ministry during the mid 1930s. This specification had sought a new generation of twin-engined medium bombers suitable for "worldwide use". Further requirements of the specification included the use of a mid-mounted cantilever monoplane wing, all-metal construction. Various candidates were submitted for the specification by such manufacturers as Fairey, Boulton Paul, Handley Page and Shorts; the majority of these engines were under development at this point. In response, British aviation company Avro decided to submit their own design, designated the Avro 679, to meet Specification P.13/36. In February 1937, following consideration of the designs by the Air Ministry, Avro's design submission was selected along with Handley Page's bid being chosen as "second string".
Accordingly, during April 1937, a pair of prototypes of both designs were ordered. The resulting aircraft, named the Manchester, entered RAF service in November 1940. Although considered to be a capable aircraft in most areas, the Manchester proved to be underpowered and troubled by the unreliability of the Vulture engine; as a result, only 200 Manchesters were constructed and the
Royal Canadian Navy
The Royal Canadian Navy is the naval force of Canada. The RCN is one of three environmental commands within the unified Canadian Armed Forces; as of 2017, Canada's navy operates 12 frigates, 4 patrol submarines, 12 coastal defence vessels and 8 unarmed patrol/training vessels, as well as several auxiliary vessels. The Royal Canadian Navy consists of 8,500 Regular Force and 5,100 Primary Reserve sailors, supported by 5,300 civilians. Vice-Admiral Ron Lloyd is the current Commander of the Royal Canadian Navy and Chief of the Naval Staff. Founded in 1910 as the Naval Service of Canada and given royal sanction on 29 August 1911, the Royal Canadian Navy was amalgamated with the Royal Canadian Air Force and the Canadian Army to form the unified Canadian Armed Forces in 1968, after which it was known as "Maritime Command" until 2011. In 2011, its historical title of "Royal Canadian Navy" was restored. Over the course of its history, the RCN has served in the First and Second World Wars, the Korean War, the Persian Gulf War, the War in Afghanistan and numerous United Nations peacekeeping missions and NATO operations.
Established following the introduction of the Naval Service Act by Prime Minister Sir Wilfrid Laurier, the Naval Service of Canada was intended as a distinct naval force for Canada, should the need arise, could be placed under British control. The bill received royal assent on 4 May 1910. Equipped with two former Royal Navy vessels, HMCS Niobe and HMCS Rainbow, King George V granted permission for the service to be known as the Royal Canadian Navy on 29 August 1911. During the first years of the First World War, the RCN's six-vessel naval force patrolled both the North American west and east coasts to deter the German naval threat, with a seventh ship, HMCS Shearwater joining the force in 1915. Just before the end of the war in 1918, the Royal Canadian Naval Air Service was established with the purpose of carrying out anti-submarine operations. After the war, the Royal Canadian Navy took over certain responsibilities of the Department of Transport's Marine Service, started to build its fleet, with the first warships designed for the RCN being commissioned in 1932.
At the outbreak of the Second World War, the Navy had 145 officers and 1,674 men. During the Second World War, the Royal Canadian Navy expanded ultimately gaining responsibility for the entire Northwest Atlantic theatre of war. By the end of the war, the RCN had become the fifth-largest navy in the world after the United States Navy, the Royal Navy, the Imperial Japanese Navy, the Soviet Navy, with over 900 vessels and 375 combat ships. During the Battle of the Atlantic, the RCN sank 31 U-boats and sank or captured 42 enemy surface vessels, while completing 25,343 merchant crossings; the Navy lost 1,797 sailors in the war. In 1940–41, the Royal Canadian Navy Reserves scheme for training yacht club members developed the first central registry system. From 1950 to 1955, during the Korean War, Canadian destroyers maintained a presence off the Korean peninsula, engaging in shore bombardments and maritime interdiction. During the Cold War, the Navy developed an anti-submarine capability to counter the growing Soviet naval threat.
In the 1960s, the Royal Canadian Navy retired most of its Second World War vessels, further developed its anti-submarine warfare capabilities by acquiring the Sikorsky CH-124 Sea King, pioneered the use of large maritime helicopters on small surface vessels. At that time, Canada was operating an aircraft carrier, HMCS Bonaventure, flying the McDonnell F2H Banshee fighter jet until 1962, as well as various other anti-submarine aircraft. From 1964 through 1968, under the Liberal government of Lester B. Pearson, the Royal Canadian Navy, Royal Canadian Air Force and Canadian Army were amalgamated to form the unified Canadian Forces; this process was overseen by then–Defence Minister Paul Hellyer. The controversial merger resulted in the abolition of the Royal Canadian Navy as a separate legal entity. All personnel and aircraft became part of Maritime Command, an element of the Canadian Armed Forces; the traditional naval uniform was eliminated and all naval personnel were required to wear the new Canadian Armed Forces rifle green uniform, adopted by former Royal Canadian Air Force and Canadian Army personnel.
Ship-borne aircraft continued to be under the command of MARCOM, while shore-based patrol aircraft of the former Royal Canadian Air Force were transferred to MARCOM. In 1975 Air Command was formed and all maritime aircraft were transferred to Air Command's Maritime Air Group; the unification of the Canadian Forces in 1968 was the first time that a nation with a modern military combined its separate naval and air elements into a single service. The 1970s saw the addition of four Iroquois-class destroyers, which were updated to air defence destroyers, in the late 1980s and 1990s the construction of twelve Halifax-class frigates and the purchase of the Victoria-class submarines. In 1990, Canada deployed three warships to support Operation Friction. In the decade, ships were deployed to patrol the Adriatic Sea during the Yugoslav Wars and the Kosovo War. More Maritime Command provided vessels to serve as a part of Operation Apollo and to combat piracy off the coast of Somalia. Following the Official Languages Act enshrinement in 1969, MARCOM instituted the French Language Unit, which constituted a francophone unit with the navy.
The first was HMCS Ottawa. In the 1980s and 1990s, women were accepted into the fleet, with the submarine service the last to allow them, beginning in 2001; some of the c
