NAMMO: In­no­va­tive 40 mm pro­gram­mable am­mu­ni­tion

Vayu Aerospace and Defence - - Cover Story -

In com­bat sit­u­a­tions, the en­emy avoids di­rect fire by hid­ing be­hind ob­sta­cles, which pro­vides a tac­ti­cal chal­lenge for own troops. In­no­va­tively, Nammo de­vel­oped the pro­gram­mable am­mu­ni­tion con­cept to give forces a re­li­able ad­van­tage, pro­vid­ing a flex­i­ble and ef­fec­tive so­lu­tion to a com­mon war sit­u­a­tion. Tech­no­log­i­cal ad­vances have made the bat­tle­field more dy­namic than ever, which means weapon sys­tems must quickly adapt to counter threats. Be­fore Nammo de­vel­oped its pro­gram­mable am­mu­ni­tion tech­nol­ogy, con­ven­tional 40 mm am­mu­ni­tion rounds had not changed for over 40 years.

In 2002, Nammo ini­ti­ated a tech­nol­ogy pro­gramme to ex­plore pro­gram­mable am­mu­ni­tion to in­tro­duce more ca­pa­bil­ity for each round. With in­tro­duc­tion of the 40 mm x 53 MK285 Pro­gram­mable Pre-frag­mented High Ex­plo­sive (PPHE), Nammo be­came the first com­pany to qual­ify pro­gram­mable am­mu­ni­tion for 40 mm Au­to­matic Grenade Launch­ers (AGL).

Nammo’s in­no­va­tive 40 mm pro­gram­mable am­mu­ni­tion tech­nol­ogy al­lows the burst dis­tance against en­emy troops to be pro­grammed ac­cu­rately di­rectly into the round. This achieves more pre­cise tar­get­ing in de­filade (for ex­am­ple, trenches, rooftops or in­side build­ings) and en­ables friendly troops to neu­tralise en­emy forces that are avoid­ing di­rect fire.

Demon­stra­tions have also proven this round to be very ef­fec­tive against Un­manned Aerial Ve­hi­cles (UAVs). Nammo’s 40 mm x 53 C171 Pro­gram­mable Pre-frag­mented High Ex­plo­sive – Ra­dio Fre­quency (PPHE-RF), fur­ther im­proves adapt­abil­ity by in­cor­po­rat­ing a wire­less com­mu­ni­ca­tion so­lu­tion to pro­gramme the am­mu­ni­tion. The 40mmx53 High Ex­plo­sive Dual Pur­pose Ra­dio Fre­quency (NM 264) (HEDP-RF), has also been de­vel­oped with wire­less pro­gram­ming, and al­lows for dif­fer­ent tar­get sce­nar­ios due to its HEDP and/ or RF func­tions.

Con­ve­nient and cost-ef­fec­tive, these am­mu­ni­tion so­lu­tions can eas­ily be in­te­grated into ex­ist­ing weapon plat­forms and fire-con­trol sys­tems for an added ad­van­tage in the mod­ern-day bat­tle­field. The stand­alone Man­ual Pro­gram­ming Unit (MPU) also en­ables pro­gram­ming with­out a fire-con­trol sys­tem.
