20mm MK2 Mod 0 Disintegrating Metallic Link.
See more information below...
Add an essential piece of Cold War–era naval aviation history to your collection with the 20mm MK2 Mod 0 Disintegrating Metallic Link, originally designed for use with the U.S. Navy’s 20mm Mk 12 automatic cannon. Manufactured to military specifications, this steel link was engineered to secure 20×110mm ammunition and feed it reliably into one of the Navy’s most widely deployed aircraft guns of the 1950s–1970s.
The Mk 12 cannon became a cornerstone of U.S. Navy and Marine Corps aircraft armament beginning in the mid-1950s. Light, compact, and capable of a significantly higher rate of fire than the World War II–era Hispano-based guns it replaced, the Mk 12 equipped several generations of carrier-based fighters and attack aircraft.
The 20mm MK2 Mod 0 link was developed specifically to support the Mk 12’s demanding operational environment. Designed as a disintegrating metallic link, it allowed individual links to separate cleanly after each round was chambered—critical for reliable operation aboard carrier aircraft subjected to intense vibration, rapid maneuvers, and harsh maritime conditions.
This link is historically associated with iconic Navy and Marine Corps aircraft, including:
F9F Cougar
F11F Tiger
FJ-4 Fury
A-4 Skyhawk
A-7 Corsair II (early variants)
Because of its long service life and wide adoption, the MK2 Mod 0 link remains an important and recognizable component for collectors of U.S. naval aviation ordnance.
These links are ideal for:
Naval aviation collectors
Cold War aircraft restoration projects
Museum displays
Inert ammunition belt builds
Historic ordnance collections
Each piece is an authentic artifact from the evolution of post-Korean War U.S. aircraft weaponry, making it a standout addition to any display of 20mm ammunition or Mk 12-related equipment.
