The Mitsubishi Ki-147 I-Gо̄ Model 1 Kо̄ was a radio-guided air-to-surface missile used by Japan in World War II. Rather than the pulsejet engine used by the V-1 and JB-2 Rockets, the Ki-147 relied on a rocket motor powered by catalyzed hydrogen peroxide. Two variants were produced: "I-Gо̄ A" with a 800 kg warhead, and "I-Gо̄ B" with a 300 kg warhead, both with otherwise similar specifications.

The "I-Gо̄ A" was to be launched from a Ki-48 light bomber, and steered towards the target the remainder of the way. American intelligence reports suspected that the missile was intended for anti-ship use when kamikaze strikes proved ineffective. Despite a final standoff distance of 4km, the design was withdrawn when planners surmised that the planes carrying the bombs would themselves be vulnerable to attack.[1]

Battlefield V[]

The Ki-147 Rocket is a Squad Reinforcement featured in Battlefield V. It was introduced in the fifth Tides of War chapter, War In The Pacific. The I-Go is available for the Imperial Japanese Army and is the equivalent of the US/UK JB-2 Rocket and German V-1 Rocket.

Although identical in call-in cost, power and flight speed as its contemporaries, the Ki-147 sounds notably different to the JB-2, more akin to a conventional jet engine. This allows players on Pacific maps to determine if an incoming missile is friendly or enemy solely based on the noise it makes.
