Hello. Today I would like to suggest the addition of the ASM-A-1 Tarzon guided bomb for B-29 Superfortress. This peculiar bomb is a modified version of the British Tallboy bomb into a radio-controlled guided bomb used during the early stage of the Korean war.

This is a follow-up suggestion of my earlier “Pumpkin bomb” for B-29, so please check it out as well.


The ASM-A-1 Tarzon next to a B-29 painted as “Command Decision”, one of the most famous B-29 during the Korean war.

The Tarzon (sometimes mislabelled as “Tarzan”) was first conceived in Febuary 1945 as a huge guided bomb to supplement and eventually replace the smaller VB-3 Razon guided bomb. The contract was awarded to Bell Aircraft, who repurposed the American-made T-10 bomb - itself a copy of the British “Tallboy” bomb - with the same radio guidance system of the Razon bomb.

The Tarzon was intended to be carried by a slightly modified B-29 Superfortress bombers, which only required the removal of its bomb bay doors and installing AN/ARW-38 command transmitter. The bomb was visually guided by the bombardier and aided by a flare at the tail. The guiding system is considered accurate, as it has an accuracy of within 85 meters during testing.

Other than guidance system, the Tarzon is largely similar to the Tallboy bomb it was based on, with the same filler of 2,400 kg of Torpex D1 explosives, though it is 500 kg heavier due to the addition of a guidance system.

Although development slowed down after the end of World War II, the Tarzon were pressed into the service during the Korean war. First used in December 1950, it was the largest bomb used in the war, the Tarzon were exclusively deployed by the 19th Bomber Group and were used against high-value targets. Initial missions were considered success, with 6 out of 28 bombs caused the destruction of key targets in North Korea, including an hydroelectric dam and a weapon factory. Because of this ,the USAF would have later placed an order of 1,000 bombs to be built.

However, the Tarzon’s career would met an abrupt end a few months later. Between March - April 1951, two Tarzons suffered a premature detonation on board due to a faulty arming wiring at the tail, resulting into the destruction of the aircraft that carried it. Although modifications were made to solve the problem, the damage was done; the bomb was deemed unsafe and can only be effectively deployed in clear day due to visual guidance. In addition, the advent of jet fighters and increased maintenance costs rendered the weapon unfeasible for further deployment. Thus, the Tarzon project were finally cancelled within the same year.
