Calian Group has locked in one of its largest defence contracts yet: a 15-year agreement to keep supporting the British Army's collective training program, this time as part of Raytheon UK's Omnia Training consortium.

The deal

Calian UK, the company's British subsidiary, will support the Army's Collective Training Service (ACTS) starting October 2026. The agreement carries approximately CAD$296 million (£159 million) in contracted base revenue over its 15-year term.

ACTS picks up where Project NUMIDIAN leaves off. That contract, which Calian has run for years, wraps this fall. The new deal extends the company's footprint in British military training without a gap.

Raytheon UK leads the Omnia Training consortium as ACTS prime contractor. Raytheon UK is an RTX business.

What Calian actually does

Collective training puts soldiers, commanders and allied forces through realistic operational scenarios together, sharpening coordination and interoperability before anyone deploys. Under NUMIDIAN, Calian built specialized training designed to expose British Army units to contemporary, high-pressure threats.

ACTS keeps that mission going, with Calian delivering specialist training services as part of a broader push to modernize British Army training through digital, synthetic and integrated capabilities.

"Military readiness begins long before a mission starts, it begins with training that prepares troops to operate with confidence in complex, high-pressure environments," said Chris Pogue, president, defence and space, Calian.

Why it matters

Fifteen years is a long runway. For Calian, ACTS locks in recurring revenue and cements the company as a long-term fixture in UK defence training infrastructure, not just a contractor cycling through renewals.

It also strengthens Calian's broader position across UK, European and NATO training and readiness work. The company brings decades of experience in collective training, simulation, systems engineering and interoperability, capabilities increasingly in demand as allied militaries prepare for multi-domain operations.

James Gray, Managing Director and chief executive of Raytheon UK, framed the consortium as a bet on that combined expertise.

"Omnia Training brings together world-class organizations with proven expertise in military training and simulation," Gray said. "Our UK-based team of innovators, engineers and experts will give soldiers and commanders a new level of training realism and set an example for effective collaboration between the army and industry."

The bigger picture

The ACTS win adds to a growing list of long-duration training and readiness contracts across allied militaries as NATO members lean into modernization. For Calian, it's a signal that its training pedigree, built over years with the British Army, travels well into next-generation program structures.
