None. X-1 (or SS X-1) [ 1] was a United States Navy Midget Submarine designed under project SCB 65. Laid down on 8 June 1954, at Deer Park, Long Island, New York, by the Engine Division of Fairchild Engine and Airplane Corporation. Launched on 7 September 1955, at Oyster Bay, Long Island, by Jakobson Shipyard. Delivered to the Navy on 6 October ...
Hercules X-1. Hercules X-1 (Her X-1), also known as 4U1656+35, is a moderately strong X-ray binary source first studied by the Uhuru satellite . It is composed of a neutron star accreting matter from a normal star (HZ Her) probably due to Roche lobe overflow.
Vela X-1 is a pulsing, eclipsing high-mass X-ray binary (HMXB) system, associated with the Uhuru source 4U 0900-40 and the supergiant star HD 77581. The X-ray emission of the neutron star is caused by the capture and accretion of matter from the stellar wind of the supergiant companion. Vela X-1 is the prototypical detached HMXB.
The Orbital Sciences X-34 was intended to be a low-cost testbed for demonstrating "key technologies" that could be integrated into the Reusable Launch Vehicle program. It was intended to be an autonomous pilotless craft powered by a " Fastrac " liquid-propellant rocket engine, capable of reaching Mach 8 and performing 25 test flights per year.

ASTM A325. ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength. It defines mechanical properties for bolts that range from ⁄ to 1⁄ inches (13 to 38 mm) in diameter. [ 1]
The real X-3 was the first fully operational x-craft but was lost during a training exercise although the crew escaped using Davis escape apparatus. X-1 and X-2 were in reality allocated to a submarine cruiser (scrapped 1936) and a captured Italian submarine, the latter later receiving the Pennant Number P711 instead.
1/2 + 1/4 + 1/8 + 1/16 + ⋯. First six summands drawn as portions of a square. The geometric series on the real line. In mathematics, the infinite series 1 2 + 1 4 + 1 8 + 1 16 + ··· is an elementary example of a geometric series that converges absolutely. The sum of the series is 1. In summation notation ...
