Herndon-based Deltek said last week it has bought Austin-based project management company Acumen, marking the company’s first acquisition in two years.

Acumen’s software is meant to help project managers at companies from defense contractors to construction firms manage their tasks.

Michael Corkery, Deltek’s chief executive, said the purchase will expand Deltek’s software capabilities as well as its portfolio of customers. Acumen, he said, has a particularly strong presence in the energy and oil and gas industries.

Corkery said Deltek plans to maintain Acumen’s 18-employee Austin office. The company is not disclosing the purchase price.

The deal is Deltek’s first since being acquired by private-equity firm Thoma Bravo last year, and Corkery said Deltek is weighing other buys. “We’ll be disciplined but opportunistic,” he said.

Orbital sets new test date

Following a successful launch of its Antares rocket in April, Dulles-based Orbital Sciences has scheduled for mid-September the next trial in its effort to resupply the International Space Station.

The test would serve as a demonstration mission, meaning it is essentially a dress rehearsal. If successful, Orbital could complete the first of eight resupply missions before the end of the year, said Kurt Eberly, deputy program manager of the company’s Antares rocket program.

Still, Orbital noted that the shifting schedule at the Virginia Commercial Space Flight Authority Mid-Atlantic Regional Spaceport facility on Wallops Island leaves open the possibility that Orbital’s test could happen as early as the end of August.

As the schedule stands, Orbital is scheduled to connect with the space station on Sept. 22 as part of the demonstration. There it will drop off cargo and take away the station’s trash.

General Dynamics consolidates

Falls Church-based defense contracting giant General Dynamics said last week that it will consolidate its armament and technical products unit into its ordnance and tactical systems business to improve its business structure.

As a result, General Dynamics will close the armament and technical products unit’s Charlotte, N.C., headquarters by the end of the year. Rob Doolittle, a company spokesman, said some jobs will be relocated, but it’s not yet clear how many will be cut.

The armaments unit has about 2,500 workers, the ordnance and tactical systems business about 3,500.

Michael S. Wilson, president of the ordnance and tactical systems business, has been selected to lead the consolidated business, which will be based in St. Petersburg, Fla.

“This is a reflection of the mandate to make sure that we’re structured to appropriately face the market that we have today,” Doolittle said.

Agile Defense protest denied

The Government Accountability Office has denied a protest filed by Fairfax-based Agile Defense against a Defense Information Systems Agency contract awarded to Alexandria-based Advanced Systems Development for IT services.

Of the dozen proposals DISA received, Agile’s had the lowest price at just shy of $114 million, but the agency gave it an unacceptable rating for technical approach and staffing plan. Agile disputed the rating, but the GAO said the evaluation was reasonable.
