French defence services company DCI has acquired a 95% stake in Vigie Aviation, a company that provides maritime surveillance services to the French state.
DCI acquired the majority shareholding from its partner, French aerospace company Chalair Aviation.
The move comes after DCI and Chalair acquired a "majority stake" in Vigie Aviation in May 2013.
DCI said on 30 June that it will now "recapitalise" Vigie.
Vigie provides airborne maritime surveillance services relating to search-and-rescue and pollution control missions. The company - based in the west of France - also provides coastline monitoring services.
DCI, for its part, was established in 1972 to assist French companies in the sale of goods to foreign markets.
