General Dynamics IT also protested Leidos' award. GAO denied that protest in a separate decision June 11.

GDIT is an incumbent for at least part of the work that will fall under the $7.7 billion network services portion of the Navy's Next Generation Enterprise Networks Recompete.

Leidos will provide "base network services ... such as electronic software delivery, end user core build, endpoint detection, logistics management, network operations, security operations, service desk, transport and virtualization services."

HPI Federal LLC will receive up to $1.4 billion to provide new hardware under the first piece of NGEN-R.

The latest extension adds at least four months to incumbent vendor Perspecta's current contract.

GDIT will continue to provide core IT services to Navy operations outside the lower 48 states at 54 overseas sites and across 10 countries.
