M777
The M777 (M777A2) is a lightweight 155 mm towed howitzer—air-transportable, titanium-built, and combat-proven from Iraq to Ukraine.
A lightweight, air-transportable 155 mm L/39 towed howitzer, fielded from 2005 by the US Marine Corps and now in service with a dozen nations including Ukraine.
Overview
The M777, known informally as the “Triple-Seven,” is a towed 155 mm artillery piece whose titanium and aluminium construction cuts weight to roughly half that of comparable legacy guns, allowing it to be underslung by medium-lift helicopters and air-dropped. First fielded by the US Marine Corps in 2005, it now equips the US, UK, Canada, Australia, India, Colombia, Saudi Arabia and Ukraine, with more than 1,250 examples produced. In the age of drone-cued counter-battery fire, the M777’s manual operation and towed footprint make it more vulnerable than self-propelled systems, yet its precision—delivered through GPS-guided M982 Excalibur rounds—keeps it relevant on modern battlefields.
