On 3 January 1942, fifty-one Hawker Hurricane fighters reached Singapore, the most substantial reinforcement of RAF fighter strength since the Japanese invasion of Malaya had begun almost a month earlier. The Hurricanes arrived with the advance parties of Nos. 17, 135, 136 and 232 Squadrons, whose pilots and groundcrew were to form the core of a renewed fighter defence for the colony as Japanese forces pressed south through the peninsula.
Malaya’s Faltering Air Defence
Since Japanese landings in northern Malaya on 8 December 1941, squadrons of the Royal Air Force, the Royal Australian Air Force and the Royal New Zealand Air Force flying the Brewster Buffalo had carried the weight of the air war over Malaya. Buffalo units suffered heavy losses in the air and on the ground as Japanese bombers and fighters struck airfields the length of the peninsula in a sustained campaign. Several squadrons were reduced to a handful of serviceable aircraft, and surviving pilots and groundcrews were pulled back as forward airfields in northern and central Malaya fell to the advancing Japanese. By the turn of the year, Allied squadrons had been driven back repeatedly, and Singapore had become the last significant base for what remained of Malaya’s fighter force. Reinforcement was needed urgently, and the arrival of Hawker Hurricanes in Singapore represented the RAF’s principal response.
Diverted from Other Theatres
The Hurricanes were sent as the Allied fighter force in Malaya suffered mounting losses and Japanese air operations placed increasing pressure on the remaining Buffalo squadrons. Among the opponents encountered was the Imperial Japanese Army Air Force’s Nakajima Ki-43, which RAF Hurricane pilots would later meet over Singapore. The Ki-43 should not be confused with the Imperial Japanese Navy’s Mitsubishi A6M Zero, which supported Japan’s parallel advances elsewhere in the Pacific and South East Asia. The Hurricane, though no longer in the front line of the fighting over Britain and Europe, remained a rugged and proven design. It had already fought in France, in the Battle of Britain and in North Africa, and its sturdy construction and forgiving handling suited it to improvised airfields and a hurried deployment overseas. Aircraft earmarked for other commitments were redirected to the Far East as the situation in Malaya worsened. The batch sent to Singapore were tropicalised Hurricane IIBs, fitted with the Vokes air filter used on aircraft serving in hot and dusty climates.
Arrival and Assembly at Seletar
The Hurricanes reached Singapore shipped in crates, and had to be unpacked, assembled and tested before they could fly operationally. Reassembly work at RAF Seletar fell to No. 151 Maintenance Unit, the RAF’s servicing unit at the station, which remained responsible for preparing aircraft there until Singapore fell the following month. Around two dozen pilots came ashore with the advance parties. These were advance parties rather than four complete squadrons. The arriving pilots, groundcrew and newly assembled Hurricanes contributed to the fighter reinforcement being organised in Singapore, including No. 232 Squadron, while Nos. 135 and 136 Squadrons subsequently operated elsewhere in the Far East.
From Crates to Combat
By the third week of January, No. 232 Squadron was flying Hurricanes operationally over Singapore. In its first combats the squadron met Japanese bomber formations and fighter escorts, including Ki-43s. The new fighter gave RAF pilots a more capable aircraft, but its arrival did not alter the wider imbalance facing the defenders. Later in January, No. 488 Squadron RNZAF, which had flown Buffaloes since the Malayan Campaign began, also re-equipped with Hurricanes as its own losses mounted and replacement aircraft became available.
The Limits of the Reinforcement
The reinforcement gave Singapore’s defenders a more capable fighter, but Japan’s advantage in numbers, tactical experience and freedom to choose when and where to strike remained decisive. Pilots were committed to combat with little time to acclimatise, and groundcrews worked to keep aircraft serviceable under repeated air attack on the airfields themselves. By the opening of the battle for Singapore Island in February, only a small Hurricane force remained available at Kallang. The surviving fighters continued to intercept Japanese raids as the ground battle closed around the island, but the shrinking number of serviceable aircraft left little capacity to contest Japanese air operations.
Withdrawal to Sumatra
As the defence of Singapore contracted in early February, surviving Hurricane strength was progressively withdrawn towards Sumatra. Kallang remained the principal fighter airfield on the island during the final phase, but the deteriorating ground and air situation made sustained operations increasingly difficult. No. 488 Squadron’s remaining Hurricanes were likewise withdrawn from Singapore to Sumatra in early February. Singapore itself surrendered on 15 February 1942, six weeks after the Hurricanes had first arrived. The episode stands as one of the earliest uses of the Hurricane in the Far East, and it illustrates how thinly RAF resources were stretched across the world during the opening months of the war against Japan.
