York Space Systems (NYSE: YSS), based in Denver, has been awarded a contract with a new U.S. government customer for a national security mission, according to a company statement.

The contract will deploy York's M-CLASS spacecraft platform, which the company describes as its largest and most powerful. Financial terms and specific mission details were not disclosed, as the program's scope is controlled.

The award brings York's total active mission sets under contract to nine. The company said the new program expands its portfolio beyond existing tactical communications capabilities into additional mission areas.

"This is an important program for York to support and a strong validation of the capabilities we've built over the last decade," said Dirk Wallinger, CEO of York.

Melanie Preisser, General Manager and Executive Vice President at York, said the award "reflects the confidence the U.S. government has in our ability to deliver resilient, mission-ready systems on accelerated timelines."
