431:. The 1888 ship had her steam machinery removed and replaced by four Derwents in 1950–1951. The purpose of this was to conduct research on the friction and drag produced by a ship hull in real-life conditions. Jets were preferable to marine propellers or paddles as these would have created a disturbance in the water, and the force exerted by them was harder to measure. The four engines could propel the

By 1941 it was obvious to all that the arrangement was not working; Whittle was constantly frustrated by what he was seeing as Rover's inability to deliver production-quality parts for a test engine and became increasingly vocal about his complaints. Likewise, Rover was losing interest in the project

was also aware of the potential of a more efficient design that removed the Power Jets' "folded" layout with a straight-through airflow. It would also simplify production. This layout had already been used by
Whittle in his drawings of the W2Y and W3X and was also being pursued by the

division, directed by Hooker, which was naturally suited to jet engine work. Hives agreed to supply key parts to help the project along. Eventually, by mutual agreement between the

Problems were soon ironed out, and the original /23 design was ready for flight by late 1943. This gave the team some breathing room, so they redesigned the /26's inlets for increased airflow and thrust. Adding improved fuel and oil systems, the newly named
