Lockheed Martin has acquired the Amor Group, the Glasgow-headquartered IT systems specialist operating in the energy, transport and public services sectors.
Amor's products help oil and gas operators protect production assets and its systems are also used in airports. Amor clients include airport operator BAA, NHS Scotland and Shell. The value of the acquisition has not been disclosed.
Amor Group is a privately-held company with more than 500 employees across seven facilities in the UK, with a presence in 15 additional countries.
Lockheed Martin CEO Marillyn Hewson said: "We're pleased to welcome the talented Amor Group team to Lockheed Martin and look forward to offering new technologies to our global customers."
Amor Group CEO John Innes said: "Our success is a direct result of our talented and dedicated employees and we're excited that this combination will enable us to continue to expand our reach and grow our business."
Innes is expected to become a "non-executive advisor" to the business once the deal is completed.
For its transportation customers Amor Group has developed a variety of systems, including the Chroma Airport Suite, which is operational at more than 75 airports worldwide. This offering complements Lockheed Martin's work with the US Federal Aviation Administration and several global customers.
There has so far been no say on whether there will be any staff cuts or other restructuring as a result of the acquisition, although there is speculation that the headcount will actually be increased.
TechMarketView analyst Georgina O'Toole said of the deal: "Amor will be part of Lockheed's Information Systems & Global Services (IS&GS) business, more than doubling the UK headcount to over 1,000.
"The deal appears to be a good outcome for Amor's previous funders, including Scottish Enterprise, which will be pleased to see another international business investing north of the border."
