The Type 271 was a surface search radar used by the Royal Navy and allies during World War II. The first widely used naval microwave-frequency system, it was equipped with an antenna small enough to allow it to be mounted on small ships like corvettes and frigates, while its improved resolution over earlier radars allowed it to pick up a surfaced U-boat at around 3 miles (4.8 km) and its periscope alone at 900 yards (820 m).
Type 271 was the primary sub-hunting radar of HMCS Sackville. Its lighthouse-like radome can be seen above the bridge.
The cavity magnetron revolutionized radar development.
HMS Orchis was fitted with the first production 271, seen here atop the bridge.
HMS Nigeria was the first ship to mount the operational Type 273, which can be seen on the mast above the dark rectangle of her Type 284.
The Battle of the North Cape was a Second World War naval battle that occurred on 26 December 1943, as part of the Arctic campaign. The German battleship Scharnhorst, on an operation to attack Arctic convoys of war materiel from the western Allies to the Soviet Union, was brought to battle and sunk by the Royal Navy's battleship HMS Duke of York with cruisers and destroyers, including an onslaught from the destroyer HNoMS Stord of the exiled Royal Norwegian Navy, off the North Cape, Norway.
