This is an excellent original U.S. 2.75-inch Folding-Fin Aerial Rocket, or FFAR, assembled as an inert training round with a Mk 1 Mod 1 rocket motor, practice warhead, and M423-type fuze assembly. The rocket has been demilitarized for training and display purposes, and the fuze is clearly marked for inert loading only.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis example has been demilitarized and is represented as completely inert.

Early complete practice rounds were designated Mk 1, with the Mk 1 Mod 1 configuration using a Mk 1 Mod 1 motor.\u003c\/p\u003e\n\u003cp\u003eThis particular example carries a 1954 ammunition lot number, placing its manufacture before the major American involvement in Vietnam. It represents the early generation of 2.75-inch folding-fin rockets from which the later helicopter-fired system developed. The modern name “Hydra 70” was applied to the later rocket family and should not be used as the formal designation for this 1950s round.\u003c\/p\u003e\n\u003cp\u003eThe fuze tip is stamped:\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eFOR INERT\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eLOADING\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eONLY - L\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e1211970-A\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth the fuze tip and the rocket head can be unscrewed for inspection.

It does not identify the complete motor as a Mk 43. The ammunition lot ending in “54” indicates 1954 manufacture or loading.\u003c\/p\u003e\n\u003cp\u003eThe motor retains its original four spring-loaded folding stabilization fins. The fins are fully deployed and remain in excellent condition. During firing, these fins folded around the motor while it was inside the launcher tube and sprang outward after the rocket cleared the launcher, stabilizing the round in flight.\u003c\/p\u003e\n\u003cp\u003eThe complete rocket measures approximately 48\" long, has a diameter of 2.75\", and weighs approximately 20 pounds. The green paint, military markings, fuze, warhead body, motor, and fin assembly remain well preserved, with only expected age, handling wear, and minor finish loss.\u003c\/p\u003e\n\u003cp\u003eEarly 2.75-inch rockets were used during the Korean War and formed the basis for the improved low-spin rockets later carried by UH-1 Huey and AH-1 Cobra gunships in Vietnam. Later motors, including the Mk 40 and eventually the three-fin Mk 66, were specifically developed for improved performance from low-speed rotary-wing aircraft.\u003c\/p\u003e\n\u003cp\u003eWith its extensive original markings, 1954-dated motor, inert fuze, excellent green finish, and complete deployed fin assembly, this is an outstanding example of the early 2.75-inch aerial rocket system that ultimately became closely associated with American helicopter gunships during the Vietnam War.\u003cbr\u003e\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":45386006134853,"sku":"ONSV25WSO134","price":595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/files\/6A7F0672-7963-4568-B754-BB9A5BD01918.jpg?v=1784743537","url":"https:\/\/www.ima-usa.com\/products\/original-u-s-1954-dated-2-75-mk-1-mod-1-folding-fin-aerial-practice-rocket-with-m423-type-inert-fuze-inert","provider":"International Military Antiques","version":"1.0","type":"link"}
