Johore Battery



Singapore Infopedia

Background

Built in the late 1930s, Johore Battery was the main artillery battery of the British coastal artillery defence network. It was located at Cosford Road in Changi on the northeastern coast of Singapore, off Upper Changi Road North. The guns at the battery were destroyed by British forces during World War II to prevent it from falling into enemy hands. The battery was discovered after the war and the site was restored with a replica of the 150-inch gun and ammunition shell. Today, the site of the former Johore Battery is a tourist attraction.1

Background
After World War I, Britain focused on developing its naval power as its defence strategy, especially when Japan was rapidly expanding its naval strength. With Japan’s military menace looming large by the 1930s, it became vital for the British to develop Singapore as a naval base. Work proceeded at full speed,2 and Changi was chosen as the site for the Royal Artillery’s batteries to protect Sembawang Naval Base against attacks from the east.3 There were six batteries protecting the naval base. The northeastern coastal batteries, together with other batteries in the southern and western coasts, made Singapore the most fortified British colony.4

The main battery in the northeastern coast was named Johore Battery in appreciation of the £500,000 contributed by Johor’s Sultan Ibrahim for the British war campaign and as a Silver Jubilee gift for King George V. Of this amount, £400,000 was used to install two of the three 15-inch guns at Johore Battery.5 These guns were the largest installed outside of Britain during World War II, and were also known as “monster guns” for their sheer size.6 The other two 15-inch guns in Singapore were mounted at Buona Vista Battery in the south.7

Description
The guns at Johore Battery were called “15-inch guns” because the shells they fired were 15 inches (38 cm) in diameter. Each gun was positioned 500 m from each other in a row. They had a 16.5-metre-long barrel, and their 360-degree traverse enabled them to target both land and sea objects. Vertical shafts led to a labyrinth of tunnels three storeys underground, and the tunnels were connected to a bunker housing the ammunition. The shells came up on hydraulic lifts and were pushed into the breech by a ram. The ammunition was capable of piercing the armour of the most powerful ship 30 km away.8

World War II
Between 5 and 12 February 1942, when the Japanese invaded Singapore from the Malay Peninsula, two of the guns at Johore Battery were turned around to fire towards land in the north and east, including enemy infantry positions in Johor. The two guns fired a total of 194 rounds.9 The coastal guns, however, had limited impact against enemy forces coming from land, as the armour-piercing ammunition designed for seaborne targets failed to explode when the shells landed on soft earth.10 The battery was also not stocked with high-explosive rounds suitable for destroying enemy infantry and artillery.11

On the night of 12 February 1942, the British destroyed the guns at Johore Battery to prevent them from falling into enemy hands.12

Postwar discovery
After the British forces left Singapore, Johore Battery was forgotten until the Singapore Prisons Service discovered it during a routine cleaning at its Abington Centre in April 1991.13 The place was then spruced up with a replica of the 15-inch gun, as well as a replica of an ammunition shell weighing over 800 kg.14

The restored Johore Battery was officially launched on 15 February 2002 as part of the 60th-anniversary commemorative programme for the fall of Singapore. The event was witnessed by some 200 former prisoners-of-war, war veterans, as well as their family members and friends. The location was also marked as a historic site by the National Heritage Board.15

In 2009, Cosford Holdings was awarded a tender by the Singapore Land Authority to revamp the premises around Johore Battery for outdoor and indoor dining.16 Today, this former military post, which still has several underground tunnels, bunkers and cannons, is a tourist attraction.17
