Arbalest Arbalest The arbalest (also arblast) was a late variation of the crossbow coming into use in Europe during the 12th century. A large weapon, the arbalest had a steel prod ("bow"). Since the arbalest was much larger than earlier crossbows, and because of the greater tensile strength of steel, it had a greater force. However, the greater draw weight was offset by the smaller powerstroke, which limited its potential in fully transferring the energy into the crossbow bolt. The strongest windlass-pulled arbalests could have up to 22 kN (5000 lbf) of force and be accurate up to 100 m. A
Laser Weapon System to the deck. Because the installation will be only a trial, LaWS will not be integrated into the ship's warfare system. In January 2018, the Navy announced a $150 million contract with Lockheed Martin for the production of two more LaWS units to be delivered in 2020; one will be fitted to while the other will be used for land-based testing. Further contract options could bring its value to $942.8 million. Laser Weapon System The AN/SEQ-3 Laser Weapon System or XN-1 LaWS is a directed-energy weapon developed by the United States Navy. The weapon was installed on for field testing
