Nike missile sites were constructed in defensive rings around major urban and industrial areas. Chicago was likely selected because of its population, the presence of several military bases, and the Gary, Indiana, steel industry. [2] Nike C-47 (Nike 1B, 1C/12H, 20A/12L-U, (8L-H)) near Portage was designed with two units nearly a mile apart.
The Sprint missile was the main weapon in the Nike-X system, intercepting enemy ICBM warheads only seconds before they exploded. Nike-X was an anti-ballistic missile (ABM) system designed in the 1960s by the United States Army to protect major cities in the United States from attacks by the Soviet Union's intercontinental ballistic missile (ICBM) fleet during the Cold War.
In the recent past, HSS was commonly available in mild steel, such as A500 grade B. Today, HSS is commonly available in mild steel, A500 grade C. Other steel grades available for HSS are A847 (weathering steel), A1065 (large sections up to 50 inch sq made with SAW process), and recently approved A1085 (higher strength, tighter tolerances than ...
Even as Nike Ajax was being tested, work started on Nike-B, later renamed Nike Hercules (MIM-14). It improved speed, range and accuracy, and could intercept ballistic missiles . The Hercules had a range of about 100 miles (160 km), a top speed in excess of 3,000 mph (4,800 km/h) and a maximum altitude of around 150,000 ft (about 46 km) [ 3 ...
Units: Hq 13th Missile Wing; Missile Support Wing; Group Operations Center and 50th (A) Squadron 1959–1990. Former combined IFC/LA location at 50°41'20"N 06°30'13" E when operating 12 x Nike Ajax missiles. This became the IFC when 50th Sq started Nike Herc ops. 36x Nike Herc. (10x Nuclear-armed) US Custodians: 43rd (C) USAAD.
On 15 November 1956, the new missile was officially renamed as the Nike Hercules, as part of DA Circular 700-22, while the Nike I becoming Nike Ajax. [ 15 ] The new design ultimately provided effective ranges on the order of 75 miles (65 nmi; 121 km) and altitudes ranging from 20,000 to 100,000 feet (6,100 to 30,500 m). [ 16 ]
MIM-3 Nike on a launcher. Bell accepted the challenge, and Project Nike was officially formed on 8 February 1945. [8] The Bell team was given the task of attacking bombers flying at 500 mph (800 km/h) or more, [N 2] at altitudes between 20,000 and 60,000 feet (6,100 and 18,300 m), and performing a 3 g turn at 40,000 feet (12,000 m).
A36 steel has a Poisson's ratio of 0.26 and a shear modulus of 11,500 ksi (79.3 GPa). [7] A36 steel in plates, bars, and shapes with a thickness of less than 8 inches (203 millimeters) has a minimum yield strength of 36 ksi (250 MPa) and ultimate tensile strength of 58–80 ksi (400–550 MPa).
