Derosa Engineering, Inc.

Derosa Engineering, Inc., a for-profit small business subchapter S corporation based in Upper Marlboro, Maryland, manufactures precision-engineered aerospace and defense components as a prime contractor exclusively (100% of recent awards), competing predominantly in full-and-open procurements with no recurring set-aside posture, though it qualifies for and occasionally wins under Total Small Business designations.

Derosa Engineering's federal footprint is narrow and specialized. The company manufactures discrete aircraft landing gear components, valve assemblies, bushings, sleeves, metering pins, landing gear pins, piston-cylinder assemblies, floating carriers, roll positioner caps, and shipping cap assemblies—parts essential to military aircraft sustainment and naval ordnance systems. Recent representative prime work includes a $51,370 purchase order from Defense Logistics Agency Aviation for 146 floating carrier assemblies (awarded January 2026), a $45,630 delivery order from DLA Aviation for valve assembly relief items (June 2025), a $38,568 delivery order from DLA Aviation for valve assembly relief components (December 2023), a $29,279 Naval Sea Systems Command purchase order for MK77 shipping cap assemblies under a Total Small Business set-aside (September 2024), and a $12,930 Naval Sea Systems Command order for MK70 igniter covers under Total Small Business (March 2024). The company also holds three active single-award Indefinite Delivery Contracts with DLA Aviation: two valued at $249,999.99 each (one covering metering and landing gear pins under Total Small Business set-aside, one for valve assembly relief items without set-aside, both extending through 2027–2030) and one $250,000 contract awarded June 2025 for bushings, sleeves, and related aviation components under Total Small Business set-aside, running through June 2030.

Customer concentration is acute. DLA Aviation accounts for 65 of 84 total awards (77%) and $1.9 million of the $2.1 million combined potential value across the prime portfolio—94% of all awards and 95% of all potential value flow through DLA Aviation and four other DLA component customers (Troop Support Construction and Equipment with $59 thousand across three awards, and the parent DLA entity with seven awards). Naval Sea Systems Command represents two awards totaling $42 thousand; the Department of the Air Force holds two awards with no stated dollar value. This concentration reflects Derosa's specialization as a manufacturer of spare parts for DLA Aviation's aircraft logistics mission rather than broad-based federal positioning.

Derosa places task orders against five named DLA Indefinite Delivery Contracts in the source: SPE4A722D5324 (four task orders, $70 thousand), SPE4A725D5243 (three task orders, $70 thousand), SPM47504D5C13 (six task orders, $22 thousand), SP047504D5C13 (three task orders), and SPM4A709D0117 (three task orders, $13 thousand). These are single-award IDCs held by Derosa itself, not vehicles on which other primes compete; they function as the company's primary contract mechanism for delivering on-demand aviation spare parts to DLA Aviation.

Activity has grown modestly in recent years: four awards in 2022, eight in 2023, eight in 2024, and fourteen in 2025, with four awards in 2026 to date. Twelve awards carrying $195 thousand in combined potential value reach ultimate completion within the next twenty-four months and face recompete. The company has no subcontract footprint—all 84 awards are prime work. Derosa operates from Upper Marlboro, Maryland, with one stated alternate performance location in Rockville, Maryland. Federal engagement dates to at least November 1996 in the source data, with continuous SAM.gov registration since April 2002. The firm's customer base, narrow product set, and full specialization in DLA Aviation aircraft spare parts manufacturing position it as a niche supplier to defense logistics rather than a diversified federal contractor.
