Munitions9M730 BurevestnikNuclear-powered nuclear-capable cruise missileThe 9M730 Burevestnik is a Russian nuclear-powered, nuclear-capable cruise missile project intended to fly at very long range along low-altitude, maneuvering routes that could complicate missile defense. Public technical data remains limited, and open-source reporting still treats its reliability, deployment status, and military value as uncertain despite Russia's repeated test claims.

Munitions3B11 nuclear projectile240 mm rocket-assisted nuclear projectileThe 3B11 nuclear projectile was a Soviet 240 mm special-purpose mortar round developed for the M240 and 2S4 Tyulpan family. Reference sources describe it as one of the 240 mm projectiles created for the system alongside high-explosive, cargo, and incendiary rounds, and note that it used the 3M15 rocket motor to extend range.

MunitionsSazhenetsSoviet 203 mm nuclear shellSazhenets was a Soviet 203 mm nuclear shell for the 2A44 artillery family used by the 2S7 Pion and 2S7M Malka heavy guns. Reference sources describe it as an improved design over Kleshchevina, but published technical detail remains limited beyond its weight, caliber, and special-charge role in the Soviet nuclear artillery arsenal.

MunitionsEnhanced Laser Guided Training Round / ELGTRLive-fire laser-guided bomb training roundThe Enhanced Laser Guided Training Round (ELGTR) is Lockheed Martin's U.S.-made live-fire training round for Paveway II laser-guided bomb employment. The company says it has been deployed since 1992, emulates GBU-10/12/16 tactics, and is compatible with F-16, F/A-18 and AV-8B platforms.

MunitionsGBU-16 Paveway II1,000-pound laser-guided bombThe GBU-16 Paveway II is a U.S.-origin laser-guided bomb that combines a 1,000-pound Mk 83-class bomb body with a Paveway II guidance kit. In the Yemen Civil War, human-rights and munitions investigators identified likely GBU-16 remnants from Saudi/UAE-led coalition airstrikes, making it part of the conflict's documented air-delivered precision-munition record.

MunitionsM28A2 Reduced-Range Practice Rocket (RRPR)227 mm reduced-range practice rocketThe M28A2 Reduced-Range Practice Rocket (RRPR) is a U.S. 227 mm live training rocket for HIMARS and M270-family crews. Lockheed Martin describes it as a training rocket that can be fired at all U.S. ranges, while Army budget documents note its inert payload section, blunt nose, and reduced maximum range of about 15 km.
