Churchill threatened to resign as First Lord of the Admiralty

Churchill pushed for higher pay and greater recreational facilities for naval staff, an increase in the building of submarines, and a renewed focus on the Royal Naval Air Service, encouraging them to experiment with how aircraft could be used for military purposes. He coined the term "seaplane" and ordered 100 to be constructed. Some Liberals objected to his levels of naval expenditure; in December 1913 he threatened to resign if his proposal for four new battleships in 1914–15 was rejected.
