Decilog, Inc.

Decilog, Inc., a for-profit corporation headquartered in Melville, New York, delivers fire control systems software engineering, digital fire control technical support, and systems integration services exclusively to the Department of the Army as a prime contractor on small-business-set-aside and full-and-open delivery orders. The vendor operates entirely on the prime side (100% of recent awards) and competes under both total small business set-asides and unrestricted full-and-open designations, with set-aside work characterizing roughly half the recent prime footprint.

The Army's dominance of Decilog's customer base is pronounced. Department of the Army Materiel Command Research Development and Engineering Command accounts for $303.8 million (51% of combined potential value) across 25 awards, while Department of the Army Materiel Command Contracting Command Picatinny Arsenal holds $152.1 million across 31 awards. These two subordinate commands represent 95% of Decilog's total combined potential value. The broader Department of the Army, including PEO Soldier, PEO Aviation, PEO Command Control Communications-Tactical, and ACC Warren, adds $25.3 million across 122 smaller awards. GSA Federal Acquisition Service rounds out the top five with 5 awards valued at $18.7 million. Together these customers account for 85% of awards and 95% of dollars.

Decilog's concrete capability portfolio centers on fire control software development, digital systems integration, and technical support for Army weapon platforms. Recent representative work includes a $25.1 million task order (September 2022, total small business set-aside) for artillery weapon system fire control support under the Fire Control Systems & Technology Engineering IDIQ; an $18.4 million delivery order (September 2022, no set-aside) for software, requirements, and integration support on M777A2 and M119A3 howitzer digital fire control systems; an $11.4 million task order (September 2022, total small business set-aside) for Lightweight Handheld Mortar Ballistic Computer (LHMBC) software development, maintenance, and testing; a $4.5 million delivery order (June 2023, no set-aside) providing ADA programming and Advanced Field Artillery Tactical Data System (AFATDS) subject matter expertise; a $1.85 million option-year modification (September 2023) for Small Arms Fire Control and Optics Technology Remote Weapon Station Fire Control engineering support; and a $1.13 million delivery order (January 2026, total small business set-aside) for technical support on AH-64E Apache helicopter computer resources. Work is performed primarily at Decilog facilities in Melville and Huntington Station, New York, as well as at original equipment manufacturer and Army engineering command sites.

Decilog's parent vehicle position is concentrated on Army IDIQs. The Fire Control Systems & Technology (FCS&T) Engineering, Technical, and Logistical Services and Support IDIQ—a $149.4 million, five-year multiple-award contract set aside for small businesses and awarded July 2022 through July 2027—serves as the primary vehicle, generating the majority of task-order volume. Four additional Army indefinite-delivery contracts (DAAA2187D0019, DAAA2194D0004, DAAE3002D1022, and DAAA2191D0001) collectively host 79 task orders. The older ARDEC Fire Control Systems & Technology Support (FCS&T) IDIQ also appears in Decilog's portfolio for earlier awards now reaching completion.

Six awards totaling $62.3 million in combined potential value reach ultimate completion within the next twenty-four months, creating a concentrated recompete window. Activity was steady through the early 2020s (4 to 5 awards per year in 2021 and 2022) but dropped sharply in 2023 (2 awards) before resuming in 2026. The vendor holds a General Services Administration multiple award schedule contract for IT professional services in addition to its Army IDIQ portfolio. Across 226 total awards in the source data since 1980, Decilog has obligated $247.6 million (42% of combined potential value), indicating selective execution against the larger pipeline of authorized task orders.
