Amentum's New Hub Cements Reston Station as a Premier Tech Corridor

RESTON, VA – February 19, 2026 – In a significant move that underscores the vitality of Northern Virginia's high-end commercial real estate market, global engineering and technology firm Amentum has signed a 45,000-square-foot lease at 1900 Reston Metro Plaza. The agreement with developer Comstock Holding Companies, Inc. establishes a new Northern Virginia hub for Amentum within the landmark Reston Station, with a planned opening in early 2027.

The new facility in the iconic, Helmut Jahn-designed tower will not just be office space; it is set to feature a state-of-the-art Technology Showcase. This move signals Amentum's strategic focus on client engagement and innovation, providing a physical stage for its advanced solutions.

"Amentum's investment in our new Northern Virginia hub at Reston Station reflects the expanding opportunities of our company and where we are headed," said Amentum's Chief Operating Officer, Steve Arnette. "This modern headquarters, featuring a next-generation Technology Showcase, will bring our teams together and serve as a destination for customers to experience our advanced engineering and technology solutions firsthand."

A Bellwether for Northern Virginia's Office Market

Amentum's decision arrives at a pivotal moment for the regional commercial real estate market. While the broader Washington, D.C. area has contended with rising office vacancy rates, which climbed towards 24.5% in mid-2025, the Amentum lease exemplifies a powerful counter-trend: the "flight to quality."

Market analysis reveals a distinct bifurcation, where premium, amenity-rich, and transit-oriented developments (TODs) are not only surviving but thriving. Northern Virginia's office market recorded positive net absorption of nearly 350,000 square feet in 2025, indicating that more space was occupied than vacated. This demand is concentrated in top-tier properties like Reston Station. Furthermore, average asking rents in Northern Virginia for such properties saw a 3% increase in 2025, a trend projected to continue with sustained growth.

This deal, following other major leases like Booz Allen Hamilton's 310,000-square-foot commitment at the same development, provides compelling evidence that modern corporations are prioritizing quality of place to attract and retain top talent. They are willing to invest in environments that offer direct transit access, modern design, and integrated lifestyle amenities.

"We are extremely excited to welcome Amentum to Reston Station,” said Tim Steffan, Chief Operating Officer of Comstock. “Their addition further reinforces Reston Station’s reputation as a hub for innovation and the premier destination for leading organizations that are seeking an easily accessible and highly amenitized work environment."

Amentum's Strategic Expansion and Innovation Focus

For Amentum, a global giant with approximately 50,000 employees, the move is more than a simple relocation; it is a calculated strategic play. Despite a recent revenue dip attributed to contract transitions, the company's fundamentals remain robust, evidenced by a total backlog that grew to $47.2 billion in early 2026. This strong pipeline is fueled by major contract wins and a strategic pivot towards high-growth markets like global nuclear energy, space systems, and critical digital infrastructure.

The planned "next-generation Technology Showcase" is central to this strategy. It is designed to be an immersive environment where government and private-sector clients can interact directly with Amentum's critical mission solutions. This physical hub will be instrumental in demonstrating the company's capabilities in securing contracts like the $3.5 billion award from the Defense Threat Reduction Agency and its work on hypersonic missile design for the UK Ministry of Defence. The showcase acts as a tangible asset for business development and reinforces the company's position at the forefront of engineering and technology.

The Magnetic Pull of a Transit-Oriented Ecosystem

Reston Station's success in attracting a tenant of Amentum's caliber lies in its carefully curated ecosystem. Spanning 90 acres around the Wiehle-Reston East Metro station, the development transcends the traditional office park model. It is a fully integrated urban center on the Silver Line, a key artery connecting the region's technology and government centers.

The 16-story, LEED-Gold certified 1900 Reston Metro Plaza is a trophy-class asset in its own right, serving as a regional headquarters for Google. But its value is magnified by the surrounding development. Reston Station features luxury residential towers, the region's only JW Marriott hotel and residences, and a vibrant retail and dining scene with names like Founding Farmers, Davio’s Northern Italian Steakhouse, and the forthcoming Ebbitt House, an expansion of the iconic D.C. institution.

This blend of world-class office space with premier lifestyle amenities creates a powerful magnetic pull. It addresses the modern workforce's demand for a seamless integration of work, life, and convenience, making it a highly competitive location against other regional hubs like Tysons. The ability to commute via Metro, grab lunch at a high-end restaurant, and live in a luxury apartment all within the same pedestrian-friendly environment is the unique selling proposition that Comstock has successfully delivered.

The addition of Amentum further cements this concentration of corporate power, placing it alongside industry leaders like Google, Booz Allen Hamilton, ICF International, and CARFAX. This clustering effect creates a dynamic innovation corridor, fostering a high-energy environment that attracts specialized talent and encourages industry collaboration. As Amentum prepares for its early 2027 opening, its new hub is poised to become a vital component of the technological and economic engine of the Dulles Corridor.
