A blockbuster bomb or cookie was any of several of the largest conventional bombs used in World War II by the Royal Air Force (RAF). The term blockbuster was originally a name coined by the press and referred to a bomb which had enough explosive power to destroy an entire street or large building through the effects of blast in conjunction with incendiary bombs.

The bombs then called Blockbusters were the RAF's HC (high capacity) bombs. These bombs had especially thin casings that allowed them to contain approximately three-quarters of their weight in explosive, with a 4000 lb bomb (nominal weight) containing about 3,000 lb (1,400 kg) of explosive (Amatol, RDX or Torpex). Most general-purpose bombs, termed "medium capacity'" (MC) by the RAF, contained 50% explosive by weight, the rest being made up of the fragmentation casing. Larger Blockbusters were made later in the war, from the original 4,000 lb (1,800 kg) version, up to 12,000 lb (5,400 kg).

 

The 4000 lb High Capacity Mark I bomb – actual weight around 3,930 lb (1,780 kg) – was a welded, cylindrical shell of 0.31 in (7.9 mm) thick steel. The body of the bomb was 30 in (76 cm) in diameter and 88 in (2.24 m) long. The nose of the bomb was conical and a 27 in (69 cm) long lightweight, empty cylindrical tail with a closed end was fitted, for a total overall length of 115 in (2.92 m). A T-section steel beam was welded to the inner surface of the bomb to strengthen it. Subsequent Mark II and Mark III HC bombs differed in detail; the conical nose was replaced with a domed nose and the number of fuzes was increased from one to three to guarantee detonation. The Mark IV bomb did not have the T-section beam and the Mark V and Mark VI bombs were versions manufactured in the United States.

 

The larger 8,000 lb (3.6 t) bomb was constructed from two 4,000 lb (1.8 t) sections, of a larger 38 in (0.97 m) diameter, that fitted together with bolts. A 12,000 lb (5,400 kg) version was created by adding a third 4000 lb section and should not be confused with the 12,000lb Tallboy ground-penetrating "earthquake" bomb.

 

The 4000-lb high-capacity design was little more than a cylinder full of explosives: it was unaerodynamic and did not have fins. By comparison the similar American "4,000 pound LC Bomb AN-M56" bomb was aerodynamically designed as other US bombs were, with a sheet metal tailfin assembly and shaped nose and aft sections. When fitted with a conical "nose piece" and a drum tail, the 1,800 kg (2 short tons) British "Blockbuster" bomb fell straight down. These bombs were designed for their blast effect, to cause damage to buildings, specifically to blow roof tiles off, so that the small 4 lb (1.8 kg) incendiary bombs could reach the building interiors. In contrast to the American AN-M56 ordnance, the cylindrical "HC"-class British-design high capacity bombs were used only by the RAF, which was the only air force with bombers with bomb bays large enough to hold them.

 

In 1947 Alfred Cecil Brooks of Stourbridge was appointed a Member of the Order of the British Empire, for creating the Blockbuster, although his citation was worded "outstanding services to the King of a nature that cannot be revealed". The local newspaper referred to him as "Blockbuster Brooks"

 

If more Blockbuster bombs are added to War Thunder, it may be a more interesting experience for players who like the UK

 

*12000 lb Tallboy and 22000 lb Grand Slam12,000 lb Tallboy and 22,000 lb Grand Slam both belong to Earthquake Bomb

 

Tallboy or Bomb, Medium Capacity, 12,000 lb was an earthquake bomb developed by the British aeronautical engineer Barnes Wallis and used by the Royal Air Force (RAF) during the Second World War.

 

The Bomb, Medium Capacity, 22,000 lb (Grand Slam) was a 22,000 lb (10 t) earthquake bomb used by RAF Bomber Command against German targets towards the end of the Second World War. The bomb was originally called Tallboy Large until the term Tallboy got into the press and the code name was replaced by "Grand Slam". The bomb was similar to a large version of the Tallboy bomb but a new design and closer to the size that its inventor, Barnes Wallis, had envisaged when he developed the idea of an earthquake bomb

 

The two bombs have a filling weight of 5,200 lb (2,400 kg) and 9,500 lb (4,309 kg) respectively, and their filling is Torpex D1

Of course, I think that if you want to add Earthquake Bomb, the game may need to make a new mechanism. When the bomber drops the bomb from a high altitude, the bomb directly inserts into the ground through its own acceleration, which makes the land vehicle player unable to find the bomb through the prompt, which will Makes land vehicle players more careful in combat

I dont think earthquake bombs would really be useful against tanks, considering most of their explosive power gets absorbed into the soil. But it would make a nice crater.

You're right, I think it might be more interesting in naval battles

我不认为地震炸弹对坦克真的有用，考虑到它们的大部分爆炸力都被土壤吸收了。 但它会成为一个很好的陨石坑。
