This bomb is totally inert and deactivated following guidelines provided by the ATF. This example is offered in very good condition, and was repainted OD green at some point. We do not know if the original blue paint was stripped or not before it was repainted. This example had a small door added to the side for reasons we are unsure of. It it complete with hinges and is secured via two small spring-loaded screws. It cannot be converted to an explosive device and is \u003cstrong\u003enot available for export.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is a Cold War\/Vietnam War-era inert Mk 15 Mod 4 Practice Bomb as used by the US Navy for aerial bombing training. It is inert, and would be filled with sand or water before use. A flash tube, which would extend throughout its transverse axis, would house a pyrotechnic signal and firing pin assembly to detonate upon impact to mark its landing relative to the target.\u003c\/p\u003e\n\u003cp\u003eThe Mk 15 is made of welded sheet metal. The empty weight is approximately 18 lbs. When filled with water (4.55 gallons) it weighs approximately 56 lbs, and 95 lbs when filled with wet sand. Under freezing conditions, a mixture of antifreeze could be used instead of water. The overall length is 41 inches with a diameter of 8 inches. This example is painted entirely OD Green. It displays well but is not the original paint, which would have been blue, and there is heavy chipping of the pain in places.\u003c\/p\u003e\n\u003cp\u003eThese bombs are impact fired signal-generating, practice bombs used for training aircrews. The practice bomb Mk 15 Mod 4 is a light cased, cylindrical bomb with a round nose and an integral box fin and cone. A flash tube, extending throughout its transverse axis, houses a pyrotechnic signal and firing pin assembly.\u003c\/p\u003e\n\u003cp\u003eThe door on the side measures roughly 13 ½ x 4” and does show the interior cavity of the bomb, but we really don’t know why the door was made. A good research project.\u003c\/p\u003e\n\u003cp\u003eComes ready to display in your Cold War collection!\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":43972633493573,"sku":"ONJR25MAOB020","price":695.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/files\/ONJR25MAOB020__01.jpg?v=1762967256","url":"https:\/\/www.ima-usa.com\/products\/original-u-s-cold-war-navy-practice-bomb-mk15-mod-4-painted-od-green-with-added-door-inert","provider":"International Military Antiques","version":"1.0","type":"link"}
