The Pentagon released a report card on its top defense suppliers this week in an effort to highlight the top performers and showcase those that aren’t doing as well.

The new report-card-like system is a way for companies to “get some feedback from us about how their performance is, relative to their peers,” Frank Kendall, the under secretary of defense for acquisition, technology and logistics, told the Army News Service. “Then they can take whatever action they think they need … to improve their ratings.”

The ratings are part of an effort, known as Better Buying Power, to improve the way the Pentagon buys everything from IT services to aircraft carriers and missiles. The companies were judged on contract performance, including whether they finished on-time and on-budget.

Officials included the 25 companies that had received the most in contracts over the past three years. The report released rates the suppliers, broken down by business segment, for the Army and the Air Force into three categories: Tier 1, 2 and 3.

Top performers included Lockheed Martin’s missiles and fire control division, General Dynamics’ aerospace division and engine manufacturer Pratt & Whitney.

Those in the “needs improvement” category were Sikorsky, L-3’s electronic systems division and General Dynamics’ combat systems division.
