1. Detonator Burster No 28 and No28A. 2. Type 6 Bursters
The burster used prior to the Burster Type 6 was the Burster No 28A which comprised a copper tube filled with seven CE pellets, a small quantity of stemmed CE, and, fitted in a brass piece, a 10 grain detonator. The burster was used on MD1 Limpets and early batches of ES6 limpets.
Up until about 1942 the RAF used the No 28 Mark I detonator-burster in certain bombs and MD1 modified the burster by reducing the size of the brass detonator holder. The percussion detonator proved to be insufficiently sensitive for use wth the soluble delays then in use with MD1 limpets. In August or September 1941 Station IX introduced a more sensitive detonator and this was adopted as the No 28A in October 1941. The No 28/28A burster did not reliably initiate limpet charges, particularly the flexible limpet, and also it was fragile.
So began the development of a replacement, the Burster Type 6 at Stations IX and XII. Orders for the Type 6 Burster Mk I were placed in September 1942 and it remained in production until October 1943. The Mark II went into production in November 1943. A total of 107,000 TYpe 6 Mks I & II bursters were manufactured. The Mark 3 was designed during the war but it was not, I believe, put into quantity production until after the war.
