RAF
Bomber Command opens the 'Battle of the Ruhr' with an attack by 442 aircraft
on Essen. Between this date and the middle of July, Bomber Command deliver
concentrated attacks against all of the major industrial cities of the
Ruhr.
Two factors can be seen to have facilitated this campaign. Firstly, the strength of Bomber Command, both in terms of the number of aircraft that it was able to deploy and the quality of the four-engined bombers (the Avro Lancaster and Handley Page Haliax) that formed an increasing proportion of the Command's front line, for the first time permitted mass attacks on German targets. Secondly,
The introduction of the 'Oboe' blind-bombing system and 'H2S' navigation and bombing radar enabled targets to be marked with some accuracy by the Pathfinder Force. The 'Battle of the Ruhr' marked the beginning of RAF Bomber Command's primary offensive against German urban and industrial targets.

12 May
A Consolidated Liberator maritime patrol aircraft of No.86 Squadron drops
a Mark 24 acoustic homing torpedo (codenamed Fido), seriously damaging
U-Boat U-456 and driving it to the surface. It is originally thought to
have been sunk as the result of subsequent attacks by a Short Sunderland
of No.423 Squadron RCAF, and the warships HMS Lagan and HMCS Drumheller.
However, it now appears that U-456 was forced to dive by approaching destroyers
and then sank because of the damage inflicted by the Liberator. This may
properly be said to mark the first successful use of an air-dropped precision
weapon in air warfare. The Sunderland and the two warships had actually
combined to sink U-753.
