The cost to build the Sembawang Naval Base and (I believe) its surrounded fortifications and guns was £28 million (1938 GBP). This is equal to £1,870 million (£1.9 billion) in 2019. We should add another £8 million for the construction of the RAF bases throughout Malaya. As a point of reference, a single KGV class battleship cost £7 million. HMS Ark Royal cost £3 million, not including aircraft. So, you've got £35 million for a Singapore strategy. What would you do differently?
