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 rockets. 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 is 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.

The Mk 4 Folding-Fin Aerial Rocket (FFAR), also known as "Mighty Mouse", is an unguided rocket used by United States military aircraft. It was 2.75 inches (70 mm) in diameter. Designed as an air-to-air weapon for interceptor aircraft to shoot down enemy bombers, it primarily saw service as an air-to-surface weapon. The FFAR has been developed into the modern Hydra 70 series, which is still in service.
