[5] [6] Boeing and Raytheon were involved in the competitive effort, but both left the competition in early 2020, leaving Lockheed Martin to develop the missile. [7] The weapon was planned to achieve initial operational capability in 2023; the initial PrSM will only be able to hit stationary targets on land, but later versions will track moving ...
A space tower is a tower that would reach outer space.To avoid an immediate need for a vehicle launched at orbital velocity to raise its perigee, a tower would have to extend above the edge of space (above the 100 km Kármán line), [26] but a far lower tower height could reduce atmospheric drag losses during ascent.
An unguided surface-to-surface missile is usually referred to as a rocket (for example, an RPG-7 or M72 LAW is an anti-tank rocket), whereas a BGM-71 TOW or AT-2 Swatter is an anti-tank guided missile. Examples of surface-to-surface missile include the MGM-140 ATACMS [2] and the Scud family of missiles. [3]
With later designs such as the RPG-7, the rocket exits the launcher with a low-powered gunpowder charge, and the main rocket motor then fires after the rocket has travelled 10 m (33 ft). In some other designs, the propellant charge burns completely within the tube.

The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad , supported by a launch control center and systems such as vehicle assembly and fueling. [ 1 ]

The 1960s saw the R-7 series continue to develop, with Vostok 1 carrying the first human into space, Voskhod carrying multiple crew members, and the first Soyuz. As of 2025, Soyuz variants are still operational and have launched over 1,100 times. The R-7 family has launched more times than any other family of orbital rockets. [3]
