Hamilton Sundstrand De Puerto Rico, Inc.

Hamilton Sundstrand De Puerto Rico, Inc., doing business as UTC Aerospace Systems, is a Puerto Rico-based aerospace components repair and maintenance specialist that serves the federal government as a prime contractor (68% of recent awards) and as a subcontractor to Boeing on defense sustainment programs. The vendor is a subsidiary of RTX Corporation (Raytheon Technologies), a major defense contractor headquartered in Arlington, Virginia, and competes full-and-open on all work without set-aside designation. Hamilton Sundstrand specializes in repair, overhaul, and sustainment of aircraft electrical and environmental control systems, primarily for rotary-wing and tactical airframes, with manufacturing operations centered at its Santa Isabel, Puerto Rico facility.

Hamilton Sundstrand's customer footprint is heavily concentrated in defense sustainment. The Air Force Sustainment Center accounts for 12 awards and $9.5 million in combined potential value (94% of total prime potential value), driven by a single-award indefinite delivery contract valued at $6.71 million awarded January 7, 2025, running through February 23, 2026, for F-16 environmental digital sensor and controller repair services. Recent delivery orders against that IDC include a $474,208 order (September 9, 2025) and a $532,100 order (April 3, 2026) for environmental control box and sensor repair work, both performing at Santa Isabel through mid-2026. The U.S. Coast Guard ranks second with 10 awards totaling $552 thousand for circuit breaker panel repairs on HC-130H/J long-range surveillance aircraft, including a $104,625 purchase order (February 27, 2024, completed May 7, 2024) and a $114,450 modification (January 29, 2025) as original equipment manufacturer sole-source work. The Navy's Naval Air Systems Command and the Air Force Materiel Command (outside the Sustainment Center) account for 11 combined awards. Activity has accelerated sharply — one award in 2020, two in 2018, but thirteen in 2025 — though only one award ($532 thousand) faces completion in the next twenty-four months.

As a Boeing subcontractor, Hamilton Sundstrand supplies electrical, hydraulic, and mechanical components and repair support to C-17 Globemaster III and P-8A Poseidon sustainment programs. Recent sub awards span annual material ordering (December 1, 2025), total sustainment support modifications (July 7, April 21, June 2, and April 30, 2025), and component-level electro-mechanical supply work on P-8A Lot 13 aircraft for Canada and Germany (September 29, 2025, and March 4, 2025). The vendor holds positions on five named Air Force IDCs and a Coast Guard basic ordering agreement. Hamilton Sundstrand's capability portfolio is grounded entirely in maintenance, repair, and rebuild of aircraft electrical components, environmental control systems, and avionics support equipment, with no development or new production work in the recent pipeline.
