Torpedo, IL-4T


IL-4T - torpedo bomber, created in the Design Bureau S.V. Ilyushin based on the long-range bomber Il-4 (DB-3F). IN aviation Naval Fleet USSR Il-4 planes were used as bombers, long-range reconnaissance, mine-loaders, as well as high-altitude and low-altitude torpedo bombers.

Possessing a long range and relatively high cruising flight speed for that time, the reconnaissance aircraft IL-4 in a short time examined significant areas of the sea surface and immediately informed the commanders about the situation in the specified areas and the targets found, called for their destruction bombers or torpedo bombers, attacked themselves most important goals. Torpedo variants of the Il-4 aircraft were armed, as a rule, with one torpedo, but some experienced pilots doubled the combat capabilities of their Il-4T aircraft, flying combat missions with two torpedoes on board.

The IL-4 minelayers could carry various types of parachute aircraft mines, including 500 and 1000 kg, as well as parachute anchors of the type "geyro" with a diameter of 1,5. Mines were laid on sea lanes, in straits, on fairways near enemy bases ports on navigable rivers. The enemy suffered significant losses from mine deliveries made by IL-4. In addition, the marine modifications of the IL-4 were armed with rocket weapons - Six PC-132 high-explosive fragmentation shells, which were suspended under the wings of the aircraft and intended to suppress the fire of anti-aircraft installations of torpedoed ships, destroy escort ships, torpedo boats and seaplanes sitting on the water.

    ... mine barriers, as well as high-altitude and low-altitude torpedo bombers
    But at the expense of high-altitude, did the author bend?
    all torpedo bombers had to drop to low altitude to launch torpedoes

      There are torpedoes that are dropped with a parachute and "walk" in a circle, waiting for the ship, and are guided by acoustics.

        it is clear, but were they in the time of IL-4?

          high-altitude (parachute) torpedoes were. and if I'm not mistaken, then in the second photo she’s parachute. I don’t know about acoustic guidance

      The worst thing is that, taking the torpedo attack course, the torpedo bomber walked in a straight line, without the maneuvers of evading anti-aircraft fire. One must have very great courage to do this.

      The main tactical technique was low-altitude torpedo throwing, when the aircraft was lowered to heights of 30-100 m and dropped a torpedo at a distance of several hundred meters or more. In the Red Army in the spring of 1944 [1], the top-mast bombing method began to be practiced, in which a bomb ricocheted from the surface of the water hit the target. In addition to low-altitude torpedo throwing, the use of parachute torpedoes was also used.

      Long range shooting was not practiced due to the low accuracy of pointing. The need to approach the attacked ship at a distance of less than a kilometer on a low-flying flight and at the same time maintain a more or less constant course made torpedo bombers very vulnerable to anti-aircraft artillery fire. It is believed that casualties among torpedo bombers in the Great Patriotic War were the highest in the Red Army Air Force... The crews of the sea DB-3F and Boston A-20 were sometimes called suicide bombers

    Iron nerves must be (or not at all) to go in a straight line for a pistol shot to attack the ship. Well, if the air defense is not thick, but if the trunks are stuck, like needles in a hedgehog ...
