M734A1 Multi-Option and M783 Point Detonating/Delay Mortar Fuze

The Department of the Army Acquisition Support Center PEO Ammunition established a single-award Master IDIQ for manufacture and delivery of M734A1 Multi-Option Fuzes for Mortars (MOFM) and M783 Point Detonating/Delay Mortar Fuzes on March 21, 2023, with ordering authority extending to March 20, 2028—approximately 20 months of remaining ordering window. The vehicle carries a shared ceiling of $412.8 million and is unrestricted, with no set-aside designations across all 10 task orders awarded to date.

L3Harris Fuzing And Ordnance Systems, Inc. dominates the vehicle, holding six of ten task orders valued at $166.2 million in combined potential value (approximately 75% of awarded volume), while Action Manufacturing Company holds four orders totaling $56 million. Ordering activity has slowed materially: the vehicle averaged 3.5 orders per year in 2023–2024 but has sustained only one order annually in 2025 and two through March 2026. The most recent task orders, awarded in March 2026, included a $38.5 million M734A1 purchase to L3Harris and a $10.1 million M783 PD/DLY manufacturing and assembly contract to Action Manufacturing, both firm-fixed-price awards with completions by October 2028 and May 2028 respectively.

The M734A1 MOFM supports 60mm, 81mm, and 120mm High Explosive and 60mm and 120mm White Phosphorous Smoke Cartridges with selectable proximity Height of Burst (60/81 PRX and 120 PRX), Impact, and Delay functions. The M783 fuze offers Impact and Delay capability on Mortar HE Cartridges for Army training and Foreign Military Sales use. Combined task-order potential value stands at $222.2 million, but obligated dollars total $279.9 million (126% of potential value), indicating substantial overobligations against stated ceilings across multiple task orders—most notably one order with $74.1 million obligated against a $20.1 million ceiling. Funding flows primarily through PEO Ammunition ($119.4 million across six orders) and general Department of the Army ($102.8 million across four orders).
