The missile contains a 1.4-kilogram (3.1 lb) warhead with a contact fuze and a single-stage solid-rocket motor that accelerates the missile to about 650 metres per second (2,100 ft/s), about Mach 2. Engagement time to the maximum effective range is about 13 seconds.
The Mod 1 probably featured an improved type fuze, moving away from the simple wick lighter design. The Mod 2 featured a simplified overall design, while the Mod 3 replaced the single-piece steel body with a two-piece plastic shell.
The 5"/54 caliber or 5"/62 caliber Mark 45 gun is fully-automated and capable of engaging surface targets in an anti-ship role, air targets in an anti-aircraft or defensive anti-missile role, and land targets in a naval gunfire support role. The gun has a range of 13 nmi (24.1 km) for 5"/54 variants [4] or 20 nmi (37.0 km) for the 5"/62 variant ...
The outputs of the Mark 1A were the same (gun bearing and elevation), except fuze time was added. The fuze time was needed because the ideal of directly hitting the fast moving aircraft with the projectile was impractical. With fuze time set into the shell, it was hoped that it would explode near enough to the target to destroy it with the ...
This led, in 1747, to 'single-fire' and eliminated the need to light the fuze before loading the shell. At this time fuzes were made of beech wood, bored out and filled with powder and cut to the required length. Experience taught that there was a minimum safe length. In 1779 the British adopted pre-cut fuze lengths giving 4, 4.5 and 5 seconds. [2]
The MK 1 is a time-fused fragmentation grenade and has 32 serrations on it. To start the fuse, the user has to pull the safety pin, then push off the cap on top of the grenade. Right before throwing, the user has to move the switch on the lever away from the grenade in order to start the fuse.
T2AAP = 3,600 Cartridges, .45 ACP Ball M1911, in 50-round Cartons, 12 cartons per M5 Ammo Can, 3 M5 Ammo Cans per rectangular cardboard box, 2 horizontally-stacked cardboard boxes per metal 20mm Mk.1 Mod.0 ammo box. Used by the Navy and Marine Corps starting in 1943 to replace the small and large M1917 wooden packing boxes.
The all-ways fuze had a minor design defect in that the hard steel ball bearing would be propelled away from the explosion as a piece of shrapnel. When used in an "offensive" application such as the No. 69 grenade, where the user was not required to take cover before throwing, there was a chance that the user could be struck and injured by the ...
