The Producers have decided to offer the film in the spirit in which it was made, as a tribute to the officers and men of H.M. Submarines, and to the Royal Navy of which they form a part.

"Truculent" was lost following a post-war accident with a Swedish oil tanker in the Thames Estuary in January 1950.
History of the oil tanker but remained afloat. Shell investigated the matter and came to the conclusion that water drops that impact steel with high velocity generates static electricity that can cause explosions in combination with cargo vapors. This only became apparent with the large sizes of the tanks of VLCC's. The solution was found by filling the cargo tanks with inert gas (IG), reducing the oxygen level such that the tank remains below the explosive limit. The use of IG is seen as the biggest step in increasing tanker safety. Ten years later however, fifty people were killed when the "Betelgeuse" exploded at Whiddy
