The engineering chlef for the Britain today has the honour of carrying out the first practical tests at sea of a ship propelled by a gas turbine, details of which appear in the October issue of "The Motor Ship." A Motor Gun Boat of the type which made the famous runs across the North Sea during the war for ball-bearings from Sweden, she is powered by two Packard V-12 supercharged engines in the wings and a Metropolitan Vickers gas turbine engine in the centre,

This view was expressed to the Air Policy Commission by R. M. Hazen, Engineering Di rector for the Allison Division of General Motors Corporation. Indianapolis, Irul. Allison bulids a large share of the turbo-jet engines now in use.
