what are these grown ups up to?



this shell and a replica of the 15-inch gun are found at the johore battery located at cosford road, off upper changi road north. the place is open on weekdays (monday to friday) from 9.00 a.m. to 5.00 p.m. admission is free. what you see at the site is a replica of one of the 'monster guns'. it is a pity the underground tunnels are not open to the public.


the johore battery comprised 3 guns. they were part of a group of 29 large coastal guns installed in singapore in the 1930s.
the johore battery's 3 weapons were among singapore's largest coastal guns. they were known as 15-inch guns because 15 inches (38cm) was the diameter of the shell they fired. their gun barrels were 16.5m long and the shells stood 1.5m high. the guns were capable of hurling these shells at battleships over 20 miles (32km) away.
they were originally called 'monster guns' when tested in england in 1934, before being sent to singapore. when world war ii started, there were only 7 of these defending the coasts of the british empire. 2 were near dover in england, and 5 in singapore.
besides the johore battery, singapore also had 15-inch guns at buona vista battery. they were located at the junction of ulu pandan and clementi roads, in the west of the island.
each of the johore battery's guns had its own ammunition bunker. these were 500m apart, arranged in a line that stretched from the present site onto what are now the runways of changi airport. though these guns were originally intended to stop an attack from the sea, two of these guns could turn around to fire to the rear, towards johor bahru. the third, the one located at this site, could only fire out to sea.
from 5 to 12 feb 1942, the 2 guns of the johore battery that could turn around fired landwards in s'pore defence. they shelled japanese infantry positions from johor bahru, just across the causeway, eastwards to the area north of tanjong punggol.
the guns of the johore battery fired 194 rounds before their demoltion by the british on 12 feb. the demolition, and the postwar upgrading of changi aerodrome, means that all that remains are the underground tunnels on the site, which once house ammunition and power plants.
