Ferrocene and its numerous derivatives have no large-scale applications, but have many niche uses that exploit their unusual structure (ligand scaffolds, pharmaceutical candidates), robustness (anti-knock formulations, precursors to materials), and redox reactions (reagents and redox standards). Use for global cooling has been proposed. [17]
Knock-down test of a 109 mph (175 km/h; 49 m/s) vortex ring gun. The vortex ring gun is an experimental non-lethal weapon for crowd control that uses high-energy vortex rings of gas to knock down people or spray them with marking ink or other chemicals. The concept was explored by the US Army starting in 1998, and by some commercial firms.
Bofors 40 mm 3P all-target programmable ammunition allows six modes including three proximity fuzing modes.This increases the flexibility and effectiveness of the gun system, which has further reduced the reaction time of the gun and it is possible to choose ammunition mode at the moment of firing, giving it the ability to switch rapidly between surface targets, air targets, and ground targets.
The main armament of the 2S25 is a 125 mm smoothbore 2A75 tank gun, which is a derivative of the 125 mm 2A46 tank gun. [13] The angles of elevation and depression for the anti-tank gun are +15° and −5° respectively. When aimed towards the stern of the vehicle, the elevation and depression of the gun changes to +17° and −3° respectively. [4]
K30 self-propelled anti-aircraft vehicles of the 11th Division Air Defense Unit of the Republic of Korea Army under live fire training. The K30 was first announced as a project in 1983 with 600 personnel conducting research and around 10 billion won spent on R&D. [6] In September 2001, the production of prototypes were done under Tong-il Heavy Industries before Doosan Infracore concluded a ...
In June 2008 a $73.8 million firm fixed price contract was awarded by the U.S. Army to BBN for 8,131 Boomerang Systems, spares and training services. [ 5 ] In 2005 Boomerang won both the DARPA "Significant Technical Achievement Award" and the Massachusetts Innovation and Technology Exchange (MITX) "Technology Influencer of the Year Award."
The LD-2000 (LD: Lu Dun, 陆盾, meaning Land Shield) SPAAGM is a Chinese developed land-based close-in weapon system with counter rocket, artillery, and mortar (C-RAM) capability. LD-2000 is based on the Chinese Navy's Type 730. Part of the HQ-6A system, it pairs with HQ-64 missiles and a Counter Battery Radar. [5]
The 2S14 Zhalo-S was built on the BTR-70 armored personnel carrier chassis, with a turret mounting an 85 mm 2A62 gun, which had identical ballistic characteristics and ammunition to the towed 2A55 anti-tank gun. The 2A62 was equipped with a muzzle brake with an efficiency up to 75-80%, able to fire 20-25 shells per minute.
