Specialty Systems, Inc.

Specialty Systems, Inc., a for-profit information technology services provider and subsidiary of Castellum Inc., operates as a prime contractor on defense engineering and software development programs for the Department of the Navy and the Department of the Air Force, competing predominantly under full-and-open (unrestricted) federal contract vehicles with no SBA set-aside designations. The vendor maintains headquarters in Toms River, New Jersey, and holds nine labor categories on the GSA Multiple Award Schedule spanning software engineering, systems administration, project management, and business analysis, with hourly rates ranging from $136.83 to $203.28 and no security-cleared positions offered.

Specialty Systems' customer concentration is heavily Navy-anchored. The Department of the Navy accounts for 71 of 139 total awards (51% of award count), with the Naval Air Systems Command Naval Air Warfare Center alone representing 27 awards valued at $391.5 million in combined potential value. The Department of the Air Force anchors the top-value ranking with 4 awards worth $900 million in combined potential value, driven primarily by the recently awarded Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) IDIQ, a $151 billion multiple-award indefinite delivery vehicle issued by the Missile Defense Agency on December 29, 2025, with an initial delivery order valued at five hundred dollars. The Office of the Secretary of Defense and Department of the Army round out the active customer set with smaller award counts.

Specialty Systems' capability portfolio centers on agile software development, systems engineering, and defense prototyping. Representative prime work includes a $2,999,982 firm-fixed-price definitive contract from Naval Air Warfare Center for agile software build and production awarded in August 2023; a $2,964,684 STTR Phase III software engineering contract from NAVAIR awarded in September 2021; a $560,000 software engineering contract from Naval Air Warfare Center for administrative and pay office modernization awarded in September 2022; and an Other Transaction Indefinite Delivery Vehicle from Naval Air Warfare Center for agile software prototype development in aircraft launch and recovery equipment, awarded December 30, 2024.

Combined potential value across 139 awards sits at $1.29 billion, with $162.6 million obligated (13% execution rate).
