Northrop Grumman Corporation's (NYSE: NOC) Sperry Marine business unit has received an order from German shipowner Martime Gesellschaft für maritime Diensleistungen mbH to supply new-generation satellite communication systems for seven ships.
The vessels -- four container ships, three gas tankers and one chemical tanker -- will be retrofitted with Sperry Marine's new digital NAVICOM F 77 marine satellite communication terminals, replacing the existing analogue Inmarsat-A systems.
