1941, Friday 05 December;
The wheels of the big twin engined bomber briefly touched ground, skipped and then touched more firmly, taking the weight of the aircraft and ran along the runway, a light spray of water flicking off the grass. It was a good landing made by an experienced pilot. The aircraft slowed and then turned and began taxiing back alongside the landing strip towards the group of men. Another was now touching down, with a further 34 aircraft enroute, some already banked up in the sky, waiting their turn.
Rear Admiral Sadaichi Matsunaga, CO of the 22 Naval Air Flotilla, stood in the light rain, a small satisfied smile on his face. Ever since the message from Admiral Yamamoto telling him that he was being reinforced with part of the Kanoya Air Group last Sunday, he’d waited in anticipation. The news of the arrival of the battleship Prince of Wales in eastern waters had sent a ripple of professional excitement around IJN senior officer circles, but for him it was also the weight of expectation on his shoulders to ensure that the threat was neutralised. His two air groups, Mihoro and Genzan, were first class units, but were equipped with the older Type 96 Rikko, while the Kanoya’s had just been equipped with the new Type 1. The Kanoya air group was arriving with three of her four Hikotai or squadrons of nine aircraft, each with three reserves.
The G4M Model 11 was the latest IJN attack bomber, replacing the G3M, although variants of that aircraft would remain in production until 1943. The G4M was a bigger aircraft, being over 3,000 lb heavier, but fitted with two Mitsubishi MK4A Kasei 11 14-cylinder air-cooled radial piston engines, each providing 1,530 hp. This delivered a top speed at altitude of 270 mph, 40 mph faster that the G3M, a cruising speed of nearly 200 mph, and an increase in range over the G3M. This performance was assisted by the continued practice of maintaining a structural lightness and an almost total lack of protection for the crew, with no armour plating or self-sealing fuel tanks.
The bomber had been guided to a stand, close to the Admiral. The aircrew climbed out and one walked over to him, stopped just short and saluted. Standing beside the Admiral, Captain Naoshiro Fujiyoishi, CO of the Kanoya Air Group, who had flown in two days before in a Ki 46, introduced him to Lt Cmdr Shichiso Miyauchi, the leader of the flight and an expert in torpedo operations. With the arrival that morning in Saigon of the transport Keiyo Maru, carrying aviation fuel, stores and more importantly Type 91 Kai 2 aerial torpedoes, the move would soon be complete.
The Tan Son Nhut airfield was crammed with aircraft far beyond its capacity, already home to the Ki-21 Sally’s of the 98th Heavy Air Regt, and the G3M Nell’s of the Genzan air group, now they were squeezing in the Kanoya’s, who’s allocated part of the airfield, despite continuing work, had the wettest and roughest ground, great care being needed when taxiing to their stands. The only saving grace was the aircrew would be accommodated in a couple of commandeered hotels in nearby Saigon, quite what their ground crews thought of that, living and working in the small tented village around the airfield, wasn’t known, but no one would be bothering to ask them anyway.
20 kilometres up the road was the old Saigon civil airfield, Thu Dau Moi, also being shared by the IJN and IJA air forces. Here they were struggling to accommodate the 48 G3M Nells of the Mihoro Air Group along with a squadron of Ki 32 light bombers and a smaller unit of Ki 59 light transports. And 90 miles south-west of Saigon, on the edge of the Mekong delta, was the Soc Trang airfield, now home of the Yamada Air group, the fighter component of 22 Air Flotilla, with 25 Zero’s and another 11 Claude fighters.
