DRDO Anti Tank Missile

The DRDO Anti-tank missile is a first generation wire-guided missile developed in India by Defence Research and Development Laboratory of Defence Research and Development Organisation. It carries a 106 mm HEAT warhead. In 1959, India started a feasibility study on a First Generation Anti Tank Missile. New General Staff Qualitative Requirements were issued and the task of preliminary study and wind testing was assigned to Department of Aeronautics and Institute of Science, Bangalore. In 1962, DRDO was granted 6,00,000 Indian Rupees to begin work on developing an Anti-Tank missile due to conflict with China in Ladakh, it has a range of 500 meters to about 2 km. After the first aerodynamic design was completed, a full-scale model of the complete configuration was tested in a wind tunnel at IISc Bangalore. At Bangalore, this model was tested for the force and momentum tests which were completed in 1961. Vibrating spoilers were used during these tests to determine control effectiveness; the ATM was designed to have a subsonic flight speed of about 90 m/s.

In 1963, the entire design was reworked for accommodating 106 mm HEAT warheads in the ATM. Defence Research and Development Laboratory, a DRDO lab, determined the propulsion motor requirement and designed the propulsion system; the propulsion motor was made of aluminium alloy. It had one for the sustainer and the other for the booster. Explosives Research & Development Laboratory, another DRDO laboratory, made the propellant compositions and developed the SUK black propulsion grains. Molybdenum inserts were used as sustainer; the booster grain had star type hole for fast burn and the sustainer was cigarette burning type for constant thrust. The actuator and gyroscope were the main components of the control and guidance system of the ATM; the Actuators were spoiler type, which gave a response time of 10 millisecond with a stay time varying from 80-20 and 20-80 milliseconds. The gyroscope developed for the ATM was a three degree freedom gyroscope; the missile was test-fired near Imarat, a village on the outskirts of Hyderabad, which held the reliability order of 65%.

The test trials were attended by Gen Bewoor Deputy Chief of Army Staff of the Indian Army. The missile hit its target 14 times. Two Indian army teams which were trained on European ATMs, Cobra and ENTAC, carried out the tests; these test did not reveal any significant difference between firing the European and indigenous ATMs. Work was still to be done on inhibition of the sustainer motor. After waiting for more than 10 years without any results, in 1969 ATM project was terminated as the Indian Army revised its General Staff Qualitative Requirements; the new GSQR extended the range of the missile from 1.6 km to 3 km. They required the man-portable missile to be capable of being mounted and fired from a mobile-launcher; this led to production of SS11B1 at Hyderabad under license from France.

Mike Garrigan

Mike Garrigan is a singer-songwriter from Greensboro, North Carolina. Garrigan grew up in Fayetteville, North Carolina and attended the University of North Carolina-Chapel Hill, where he performed in local coffee houses as a vocalist and guitarist, he is best known as the former frontman of the rock band Collapsis, which, in 2000, reached the #28 slot on the Billboard Modern Rock charts with the hit song "Automatic". He was the second and final lead guitarist for the North Carolina-based band Athenaeum, replacing Grey Brewster for their second album and continuing until the band disbanded in 2004. With former Athenaeum members, Garrigan formed a new band called the "Mike Garrigan Four", which released an EP in 2004. Since he worked as a solo artist, while continuing to play occasional shows with Mark Kano, lead singer of Athenaeum. In 2006, he released Live at the Evening Muse, a CD/DVD of a solo acoustic show he recorded at a venue in Charlotte, North Carolina in June 2005. Several of his solo albums have been supported through Kickstarter, including the 2011 release The Return of Spring.
