Army bombers took off from the naval aircraft carrier to bomb Tokyo. How do Americans do it?

1. Dismantle the machine gun in the belly turret;

2. Considering the possibility of cold weather, deicers are installed at the front and rear of the wing to prevent fuel from freezing;

3. Install ventilation steel plates around the top machine gun;

4. In order to prevent the plane from being exposed, the radio was silent during the whole operation, so the radio transceiver was useless and was dismantled;

An auxiliary fuel tank was installed in the bomb cabin. At first, a 265-gallon steel oil tank was used, but later, due to serious oil leakage, it was changed to a 225-gallon rubber oil tank. Install a 160 gallon folding rubber oil tank above the bomb bay, which can be folded and put away after using up the oil inside;

6. Install 1 10 gallon metal auxiliary fuel tank on the belly turret, so as to increase the total oil load of B-25 from 646 gallons to114/gallon;

7. Considering that it will take time to find the airport to land once you get over China, you should bring more fuel. Therefore, a 60-gallon and 10 5-gallon small fuel tanks are installed in the cockpit of the radio unit at the rear of the aircraft, and the gunner is required to continuously inject the oil in the small fuel tank into the auxiliary fuel tank of the turret during the flight, and then drill holes in the small fuel tank and throw it out of the aircraft, so that the small fuel tank can quickly sink into the sea without leaving any trace of tracking the Japanese fleet;

8. Improve the bomb hook of the bomb bay, so that it can install two 227kg blasting bombs and one 454kg incendiary bomb in a narrow space, with an auxiliary fuel tank. Incendiary bombs are cluster bombs, 128 3kg sub-incendiary bombs;

9. Considering the unreliability of the rear turret double-tube 12.7mm machine gun and the frequent jamming, it was decided to unload the rear machine gun to reduce the aircraft load. But in order to protect the plane from attacks from the rear, two wooden sticks painted black were installed at the tail to simulate the barrel of a machine gun. This scarecrow machine gun is quite effective in actual combat. From a distance, it is difficult for Japanese pilots to distinguish between true and false, but they dare not attack from behind easily.

10. Remove the Norton bombsight and install an alternative bombsight invented by pilot Captain C Ross Glinning. This is because Norton sight contains cutting-edge technology. Considering the risk of forced landing in the occupied area, it is likely to fall into the hands of the Japanese army, so it was demolished. The replacement sight invented by Rosgreen is very cheap, and the material is only worth 20 cents. Because the imaging color is not high, it was nicknamed "Mark Twain" by colleagues. Mark Twain's eyes are color-blind, so his colleagues used them to mock the sight of low color blindness.

1 1. In order to reduce the weight and avoid fire, the lighting shells were removed, leaving only two behind the armored pilot's seat for landing at night;

12. Of the 24 improved bombers, two were equipped with cameras to capture the bombing effect.
