Operation Buffalo consisted of four tests; One Tree (12.9 kilotons of TNT (54 TJ)) and Breakaway (10.8 kilotons of TNT (45 TJ)) were detonated on towers, Marcoo (1.4 kilotons of TNT (5.9 TJ)) at ground level, and the Kite (2.9 kilotons of TNT (12 TJ)) was released by a Royal Air Force (RAF) Vickers Valiant bomber from a height of 11,000 metres (35,000 ft). This was the first drop of a British nuclear weapon from an aircraft. Operation Antler in 1957 tested new, light-weight nuclear weapons. Three tests were conducted in this series: Tadje (0.93 kilotons of TNT (3.9 TJ)), Biak (5.67 kilotons of TNT (23.7 TJ)) and Taranak (26.6 kilotons of TNT (111 TJ)). The first two were conducted from towers, while the last was suspended from balloons. Tadje used cobalt pellets as a tracer for determining yield, resulting in rumours that Britain was developing a cobalt bomb.
