The building and operating of ship and shore stations also gradually fell into the hands of big companies. In the United States, mainly as a result of bankruptcies following adverse patent suit decisions, more than 400 ship and shore stations built in the preceding decade by De Forest and numerous small firms were acquired by the American Marconi company, giving it an almost total monopoly of radiotelegraphy for coastal shipping. Big European companies such as Germany's Telefunken built superpower stations of 100 kilowatts and more for shore installations.
The Navy's principal shore-to-shore missile has been the Regulus I. Developed by 1951, it resembles a swept-wing jet fighter and is operated by a turbojet engine after the initial boost. Since it can be launched from a ship's rail without the Terrier's heavy gear, it is designed particularly for submarines but has also been used on various types of warships. In the Regulus II, whose development was canceled in December 1958, the range was increased from 500 to 1,000 miles.
