Bring a classic early-generation anti-armor aerial rocket back to life on your wall, pod, or pylon display with this restored 2.75" / 70mm Mark 5 High Explosive Anti-Tank (HEAT) rocket mated to an original Mark 4 Mod 10 Folding-Fin Aerial Rocket (FFAR) motor. This piece captures the look and proportions of an early “Mighty Mouse”-era HEAT rocket while remaining completely inert and safe for static display.
The Mark 5 HEAT Warhead
The 2.75" FFAR family was developed in the late 1940s–1950s as a lightweight, modular rocket system for U.S. fighters and attack aircraft, originally fielded as the “Mighty Mouse” air-to-air rocket and later adapted for air-to-ground work. Among its early warheads was the Mark 5 HEAT head, designed to penetrate armor and hard targets using a shaped charge rather than pure blast/fragmentation.
Key historical characteristics of the live Mk 5 HEAT warhead (for reference):
- Type: High-Explosive Anti-Tank (HEAT) shaped-charge warhead
- Filler: Approximately 404 g (about 14.2 oz) of Composition B explosive behind a shaped-charge cone
- Effect: Focused armor-piercing jet intended for use against armored vehicles and hardened point targets
- Platform use: Carried on fixed-wing aircraft and, later, rotary-wing platforms using 7- and 19-tube launch pods in the FFAR family
Your warhead retains the original Explosively Formed Penetrator (EFP) (visible in the photos), preserving the correct internal geometry of the warhead cavity while remaining inert.
Mark 4 Mod 10 Folding-Fin Rocket Motor
The Mark 4 rocket motor is the classic 2.75" FFAR “Mighty Mouse” motor, an unguided, solid-fuel rocket body with folding tail fins that deploy at launch for stabilization. The Mod 10 variant was produced under U.S. military specification MIL-R-60995 for operational service, and later served as one of the standard motors for a wide variety of 2.75" warheads.
Typical characteristics for the Mk 4 motor (for reference with an HE warhead):
- Diameter: 2.75 in / 70 mm
- Motor length (approx.): 99.8 cm (39.3 in)
- Motor weight (approx.): 5.0 kg (11 lb), depending on warhead
- Propulsion: Solid-fuel rocket, folding tail fins, spin-stabilized
On display aircraft and in ordnance collections, a Mk 4 motor with a HEAT head like the Mk 5 represents the early generation of U.S. 70mm rockets that eventually evolved into the later Mk 40
and Hydra 70 / Mk 66 family.
