The Mod 1 was fission-only with a fixed 0.8 kt (3.3 TJ) yield, corresponding with the maximum fission only yield of the Mod 0; Both models were 8 in (203 mm) in diameter, 44 in (1,100 mm) long and weighed 200 lb (91 kg). The W79 was developed by Lawrence Livermore National Laboratory, starting in 1975. Production of the different mods took ...
The complex, which opened in 1992, is located on a 54-acre site at Kirtland Air Force Base in Albuquerque, New Mexico, United States, under the control of the Air Force Global Strike Command [1] It is operated by the 898th Munitions Squadron (898 MUNS) and the 377th Weapons Systems Security Squadron (377 WSSS). The facility is state of the art ...
The shell, designated a Mark 9 nuclear weapon, had a diameter of 280 mm (11.02 in), was 1380 mm (54.4 in) long and weighed 364 kg (803 lb). The M65 Atomic Cannon from which it was fired had a muzzle velocity of 625 m/s (2,060 ft/s), for a nominal range of 32 km (20 mi), and weighed 77 metric tons (85 t ).
A total of 5,250 W68 warheads were produced, the single largest production run of any American nuclear weapon model. It was manufactured starting in June 1970 and ending in June 1975. Each Poseidon missile could carry up to 14 warheads; at the peak deployment, there were 31 US Poseidon submarines with 16 missiles each, for a total of 496 ...
In 2003, a research team at NEC fabricated the first MOSFETs with a channel length of 3 nm, using the PMOS and NMOS processes. [20] [21] In 2006, a team from the Korea Advanced Institute of Science and Technology (KAIST) and the National Nano Fab Center, developed a 3 nm width multi-gate MOSFET, the world's smallest nanoelectronic device, based on gate-all-around technology.
Exploded diagram of the Mk21 reentry vehicle for the W87 [clarification needed]. The W87 is an American thermonuclear missile warhead formerly deployed on the LGM-118A Peacekeeper ("MX") ICBM. 50 MX missiles were built, each carrying up to 10 W87 warheads in multiple independently targetable reentry vehicles (MIRV), and were deployed from 1986 to 2005.
The W71 nuclear warhead Warhead being lowered into the borehole. The W71 nuclear warhead was a US thermonuclear warhead developed at Lawrence Livermore National Laboratory in California and deployed on the LIM-49A Spartan missile, a component of the Safeguard Program, an anti-ballistic missile (ABM) defense system briefly deployed by the US in the 1970s.
The warhead was the first to use a rotary chopper inverter/converter to convert the 28 volts DC supplied to the weapon to 2200 volts DC for the X-unit's capacitor bank. The warhead had both air-burst and contact-burst fuzing options, and the boosting gas system was mounted inside the pressurized portion of the warhead. [3]
