Washington-area Navy contractors have been ranked “superior suppliers” in a first-of-its-kind list released by the government to promote competition.

Business units of General Dynamics, Lockheed Martin and Northrop Grumman are included in the list, which the Navy compiled under a program known as the Superior Supplier Incentive Program. The initiative is part of the Pentagon’s overhaul of the government acquisition process, known as Better Buying Power.

The Navy’s list could act as a template for other government departments, Frank Kendall, the undersecretary of defense for acquisition, technology and logistics, said in a media briefing Friday.

“The recognition that they’re not in [the list] is going to be an incentive” for companies to talk to their government customers about areas of improvement, Kendall said.

The pilot program, which analyzed three years’ worth of data to rank contractors, was a work in progress, officials said.

“We’re going to learn what motivates industry, we’re going to learn how good we are at assessing industry performance and as we learn those things the program will evolve,” Elliott Branch, deputy assistant secretary of the Navy, said in a statement.

The Navy started out by selecting the 30 largest contractors based on “contract obligations” for assessment, said Sean Stackley, the Navy’s assistant secretary for research, development and acquisition.

Contractors were ranked based on their cost, scheduling and quality performance during the last three years, as evaluated by government program managers, Stackley said. Different business units were considered separately, so more than one unit within the same company could make it to the list.

Here are the top nine, in alphabetical order:

• General Dynamics Combat Systems

• General Dynamics Marine Systems

• General Electric Aviation

• Lockheed Mission Systems and Training

• MHSCo Sikorsky Lockheed Partnership

• Northrop Grumman Aerospace Systems

• Raytheon Integrated Defense Systems

• Raytheon Intelligence, Information and Services

• Rolls-Royce Defense Aerospace
