Pulau Ubin AMTB in 1946
The Pulau Ubin AMTB Battery was completed prior to the war with Japan, but was never armed. It was designed for two Twin 6-Pounder Guns, each with its own Director Tower. Pulau Ubin was one of three AMTB Batteries which were never armed. The other two were Changi Inner and Tanjong Tereh. The guns had been ordered but delivery was not due till mid 1942.
Whilst eventually built as an AMTB Battery, Pulau Ubin was once considered as a possible site for a 6-Inch BL Battery to be emplaced at Chek Jawa.
