Providence, R.I.-based Textron Systems is set to open a new office near the Navy Yard this summer, after winning a more than $200 million contract to design and build a ship-to-shore landing craft.

The deal, which includes options for up to eight additional craft, pays for a landingcraft that can move personnel and equipment from sea to land.

In mid-May, Textron plans to open a 6,000-square-foot office at 100 M St. SE, according to company officials.

Ellen Lord recently became president and chief executive of the Textron operating unit. She said the business is increasingly seeking work overseas as U.S. defense spending shrinks.

In 2008, about 10 percent of the company’s work was international; this year, she said that figure should be between 30 and 35 percent. Textron Systems is also looking at potential commercial applications for unmanned systems.

“It’s not really a question of if that’s going to happen, it’s when,” she said of commercial adoption.

Top aerospace companies see revenues drop

A new report from Deloitte found that the revenues of the top 20 publicly listed U.S. aerospace and defense companies grew 5.5 percent to $354.7 billion in 2012, though operating profit decreased about 2.2 percent.

According to the report, which used data from company filings and press reports, the growth in revenue was driven by commercial aircraft production, but weakening defense spending hurt profits.

Operating profit dropped to $36 billion while operating margins decreased to 10.2 percent, down from 10.9 percent in 2011, according to Deloitte.

Among the local companies included in the analysis were General Dynamics, ITT Exelis , Lockheed Martin and Science Applications International Corp .

About 250 employees to leave Lockheed

Bethesda-based Lockheed Martin said last week that nearly 250 employees will depart after accepting voluntary layoffs.

The contractor’s Gaithersburg-based information systems unit offered buyouts to about 4,000 mid-level managers in February. The company said this week that 260 employees offered to leave and 243 were approved.

All of the employees who applied were notified whether or not they were accepted by March 8; accepted employees were slated to depart on March 22.

“We are not planning additional layoffs at this time, though we will continue to evaluate our workforce needs,” a company spokeswoman said in a statement.

GAO denies Systalex

The Government Accountability Office last month denied a protest filed by Systalex of Rockville against a Census Bureau contract awarded to Prime Source Technologies of Falls Church for financial and administrative services.

Prime Source was ranked first technically with a proposed price of $21.7 million, while Systalex was ranked second and had a slightly lower price of $21.6 million. Systalex argued that its proposal was not evaluated correctly, but the GAO found that the evaluation areas it challenged would not have changed the award.
