RAF D-Day Brief

Allied air forces available for OVERLORD

Under RAF control there were 285 RAF sqns: 5,039 serviceable aircraft.

They included Allied/Commonwealth air force sqns under RAF posting strength – an additional 19 attached Fleet Air Arm/US Navy/Royal Canadian Air Force sqns with 213 serviceable aircraft. The total was thus 304 sqns; 5,252 serviceable aircraft.

The US Army Air Force operated 374 sqns with 5,294 serviceable aircraft.

The Allied total was thus: 678 Sqns: 10,546 serviceable aircraft

RAF Bomber Command

Bomber Command’s ORBAT in June 1944: 82 sqns (1,681 serviceable aircraft).

During invasion period, virtually all of Bomber Command’s operations concentrated on supporting the assault/beachhead.

There were attacks on:

• Rail and road communications, in order to isolate the invasion area (the Transportation Plan).

• German troop/gun positions, ammunition and fuel dumps.

• French ports in which German Navy fast attack craft (E-Boats)/other coastal vessels had been concentrated to interdict Allied invasion fleet.

• Bomber Command aircraft also dropped personnel/supplies to support SOE/Resistance and SIS operations in connection with the invasion.

Operations, night 5/6 June:

Bomber Command flew over 1,300 sorties against targets in Normandy and 11 aircraft were lost.

1,136 sorties despatched (670 Lancaster, 412 Halifax, 54 Mosquito) to attack 10 coastal gun batteries in the invasion area.

1,058 attacked; 5,238 tons HE and 30 tons incendiaries dropped.

This represented the greatest total sorties flown/greatest tonnage dropped on 1 night to that point in the war.

6 aircraft (4 Lancasters, 2 Halifaxes) were lost.

Bomber Command also mounted deception and EW operations:

• Op TAXABLE: No 617 Sqn (16 Lancasters) dropped precise Window (chaff) patterns at low level, in conjunction with RN deception operation, to simulate invasion convoy approaching coast at Cap d’Antifer

• Op GLIMMER: No 218 Sqn (6 Stirlings) conducted similar operation to that of No 617 Sqn, to simulate invasion convoy approaching Boulogne.

• Op TITANIC: 36 Halifaxes/Stirlings dropped dummy parachutists, rifle fire simulators, Window, 2 SAS teams to simulate airborne landings away from invasion area; 2 Stirlings lost.

• No 101 Sqn (24 Lancasters), No 214 Sqn (5 Flying Fortresses) established ABC (ground-air radio jamming) and Window barrage along line of Somme Estuary to distract enemy nightfighters from transport aircraft carrying airborne troops; 1 Lancaster lost.

• No 199 Sqn (16 Stirlings) and 4 US Army AF aircraft established jamming screen using Mandrel EW radar jammers between Littlehampton and Portland Bill, to hide real invasion fleet from German EW radar.

• Mosquito nightfighers flew 48 intruder/bomber support sorties over Luftwaffe airfields in France/Low Countries.
