Hewlett-Packard’s massive, $3.5 billion Navy contract could be in jeopardy.

The group that lost the bid—led by Virginia-based Computer Sciences Corp.—filed an official protest Monday with the U.S. Government Accountability Office.

The details of that protest were not immediately available, according to Bloomberg. In previous cases involving big-ticket contracts, losing bidders have argued government officials made the wrong decision by backing proposals that cost too much or didn’t fit the stated criteria.
