The CRV7, short for “Canadian Rocket Vehicle 7”, is a 2.75-inch (70 mm) folding-fin ground attack rocket produced by Bristol Aerospace in Winnipeg, Manitoba. It was introduced in the early 1970s as an upgraded version of the standard U.S. 2.75-inch air-to-ground rocket. It was the most powerful weapon of its class, the first with enough energy to penetrate standard Warsaw Pact aircraft hangars. The CRV7 remains one of the most powerful air-to-ground attack rockets to this day, and has slowly become the de facto standard for Western-aligned forces outside the United States. Beginning in 2021, 83,303 stored Canadian CRV7s are slated for disposal, having been removed from service from 2005 to 2007. In 2024 the Department of National Defence was considering donating the rockets to Ukraine as military aid to defend against the Russian invasion of Ukraine. An estimated 8,000 rockets have functioning warheads, while the remainder could be used for parts or modification. In September 2024 Canadian defence minister Bill Blair announced Canada would be sending 80,840 rocket motors to Ukraine over the next months, in addition to the 2,100 already shipped, along with 1,300 warheads.
