There are three main types of precision machine grinding: surface grinding, cylindrical grinding, and centerless grinding. Surface Grinding. Surface grinding is used to produce plane surfaces. The workpiece, mounted on the machine table, lies in a plane parallel to the axis of rotation of the grinding wheel. The workpiece is reciprocated and fed transversely by small increments, into the edge of the wheel until the entire surface is ground. Sometimes the wheel's face is parallel to the work surface, and the workpiece revolves on a Table under the wheel.

Most naval combat ships carry two types of search radars: surface search, to detect ships and obstacles to navigation; and air search, to keep track of'friendly aircraft and to detect approaching enemy aircraft. Surface search radars are designed for much shorter ranges than air search radars, since the maximum distance at which a surface target may be seen is generally limited by the curvature of the earth to 20 or 30 miles. The antenna beam of the surface search radar is usually very narrow in the horizontal plane in order to provide good angular resolution and fairly wide in the vertical plane to allow for the roll and pitch of the ship.

Of the wide variety of surface-to-surface, surface-to-air, air-to-surface, and air-to-air missiles developed by this and other projects, warships were most directly affected by the series of surface-to-air missiles with the popular names Terrier, Tartar, and Talos. These missiles were designed primarily for protection against fast, powerful high-altitude bombers. With their use, carriers, which had devoted much of their plane capacity to protective interceptor fighters, could accommodate greater numbers of offensive bombers.
