Default British electronic counter measures in WW2

WINDOW

‘Tin foil’ proves a success

WINDOW was first used by the RAF in a series of attacks on Hamburg: the first was on the night of 24/25 July 1943, followed in quick succession on 27/28 and 29/30 July. A fourth raid on 2 August was a failure due to a massive thunderstorm over the target. The strips 30 cm long and 1.5 cm wide were being dropped at the rate of a bundle a minute. 2000 of the strips would have appeared to Wurzburg operators as the echo of a heavy bomber. The effect, particularly on the first night, was dramatic. The entire radar system was disrupted. Searchlights were seen to be waving aimlessly; Anti-aircraft fire was hesitant and inaccurate and gave way to barrage fire; German fighter pilots were losing their cool in the general mayhem and the intercepted radio traffic showed the enemy ground controllers were hopelessly confused. 700-800 RAF aircraft dropping WINDOW had created on German radar screens the suggestion of 11,000 bombers about to attack.

The results spoke for themselves. Only 12 aircraft were lost on the first Hamburg raid - just 1.5%. On the second and third raids losses crept up a little - to 17 and 27 aircraft - but still significantly below the previous loss rates. From then on, WINDOW became routine on every flight until the end of the war. It was manufactured in varying dimensions to match different frequencies.

Default 100 Group – Decoys, spoofs & ghost bombers

In November 1943, 100 Group was created as the RAF unit responsible for all electronic and radio counter-measures. The Group used about 100 aircraft for bomber support. B-17s (Flying Fortresses) and B-24s (Liberators) carried jamming equipment and flew with the bomber stream; Halifaxes and Stirlings flew separate missions creating false radar echoes of spoof and decoy raids by non-existent ‘ghost’ squadrons using WINDOW and other devices. The Group also flew Beaufighters and Mosquito night fighters, carrying airborne radar for tracking and destroying enemy night fighters.

The B-17 Fortresses were chosen because of their ability to fly particularly high. Their radio transmitters jammed German early warning radar and fighter control communications. A German speaking crew member would operate the jamming equipment and give false instructions to Luftwaffe night-fighter pilots. The B-17s were able to fly 5,000 ft above the bomber stream, throwing out a protective electronic ‘cloak’ to help conceal the attack. Similar work was carried out by B-24 Liberator bombers.

Default Electronic ‘raids’ on D-Day

On the night of 5/6 June 1944, a few hours before the D-Day assault on Normandy, five of 100 Group’s B-17 Fortresses, together with a similar force of Lancasters, were given an unusual task: To fly back and forth across the Channel, penetrating 80 miles into France then turning around. On each inward journey WINDOW bundles were tossed out as fast as possible. Just 10 aircraft created on German early warning radar a ‘ghost’ bomber stream of hundreds of non-existent raiders, distracting the Nazis’ attention from Normandy. The decoy bombers also jammed German radio using on-board transmitters. An electronic wall, blocking all German communications, was established for several hours over northern France, masking the presence of 1,000 Allied transport aircraft on their way to drop paratroops at the start of the greatest invasion in history.

First intergrated air defence...thank you very much..cant stress enough how much of an inpact it had on the battle of britian

Once Radar was fitted to ships and certain aircraft the battle of the Atlantic started to swing in our favour

LOL...we were using radar to our advantage before the yanks were even in the war....the early warning system including radar played a huge role in Britians victory in the Battle of Britian ...radar was being used in the North Atlantic before the pacfic threatre blew up

yep.. i just forgot the word "just" from beween.

it was quite obvious that the knowlage spread trough the allies..
as we soon learned about the soviet installations..
we didn't know what they were those days.

Oh yes... now i understand...the soviets caught up pretty fast in all areas they had the brains and the manpower...it amazed me in the cold war how they intergraded their SAMs (both fixed and mobile)Radar systems and the Air Force response time....look at the yom kippur war...the Soviet sales of Air defence systems to Egypt really hammered the Israelis...it was a shock to the west because the same could have happened in a Euro conflict
