San Diego-based Solpac Construction Inc., which does business as Soltek Pacific Construction Co., received a $20.2 million U.S. Navy contract to build a multistory training building to prepare pilots to fly the next generation of fighter aircraft: the F-35C Lightning II.

Work will be done at Naval Air Station Lemoore in California’s Central Valley. The deal also includes four options and one modification; if the Navy customer exercises them all, the value of the deal will rise to just under $21 million.

The deal calls for the contractor to build a multi-story, steel-framed and reinforced concrete masonry training facility that will house full mission simulators, classrooms, briefing rooms, storage and maintenance areas, personnel support spaces and administrative spaces.

The San Diego office of NAVFAC, the Naval Facilities Engineering Command Southwest, awarded the construction deal, which the Pentagon announced on June 26.

The F-35C — also known as the Joint Strike Fighter — is the Navy version of the fifth-generation fighter program that is alternately billed as a technological marvel and the most expensive weapons program ever. Lockheed Martin Corp. (NYSE: LMT) is the aircraft’s prime contractor.
