The FFAR Mighty Mouse or Mk 4 Folding-Fin Aerial Rocket is a 2.75 inches (70 mm) diameter unguided rocket utilised by military aircraft. This rocket was primarily developed for interceptor aircraft which would utilise them for shooting down enemy bombers which proved difficult to shoot down with guns and cannons at the speeds at which they were travelling. While initially developed for air-to-air combat, the FFAR was found to be very effective when utilised in air-to-surface operations.

Unlike traditional missiles with fixed fins, the FFAR's fins were in a folded position when loaded in a launch tube. Upon the missile being launched and departed the launch tube, the folding fins would flip out into place to help stabilise the spin-rate of the rocket. While a single rocket could by itself bring down a bomber, due to it being unguided, accuracy was not on the side of the attacking pilot. To compensate for the inaccuracy of the rockets, they were usually launched in volleys to increase chances of hitting the target.

By the late 1950s, rockets had largely been removed from air-to-air service and were being fitted to helicopters for an air-to-ground role. For helicopters, a volley of rockets was found to be just as effective as a cannon, however, the rockets were lighter and did not cause recoil that the cannons produced.

The FFAR was given the nickname Mighty Mouse after the famous cartoon character of the time which featured a mouse with superpowers and the ability to fly and was known to sing a famous line "Here I come to save the day!" when he flew into action.

General info

Effective damage

The FFAR Mighty Mouse is a straight forward unguided high-explosive rocket which can be configured for either a contact fuze, timed fuze or an automatic detonation fuze once the rocket propellent has run out. If the rocket explodes within close proximity of a target aircraft or vehicle, it will still cause splash damage and still potentially disable or destroy the target.

Comparison with analogues

Give a comparative description of bombs that have firepower equal to these type of weapons.

Usage in battles

Due to the size and inaccurate nature of the FFAR Mighty Mouse, this rocket is best used against slower moving targets like bombers, hovering helicopters, aircraft parked on a runway and other lightly armoured targets. When attacking bombers, it may be necessary to fire off the entire volley of rockets in one shot to increase the chance of hitting the target. For aircraft parked on the runway, helicopters or other lightly armoured targets it may only be necessary to fire off several rockets to ensure a hit, but not the entire volley. Several rocket attacks may be required due to the inaccurate nature of these rockets.

Pros and cons

The FFAR Mighty Mouse was nicknamed after the fictional cartoon character Mighty Mouse.


  • Enough explosive value to take out a bomber
  • Lightweight


  • Extremely inaccurate, best to fire off multiples
  • Requires using many to increase chances of hitting a target
  • Like firing a shotgun, some may hit a target
