These troughs could either be laid against earthen embankments or mounted on bipod or monopod launch frames.

[1] The rocket boosters consisted of a nose cone, propellant chamber, butt plate, tail fins, and a single venturi.

The propellant chamber held three sticks of solid-propellant and was closed at the front by a nose cap.

There was also a slightly longer rocket booster, the Type 3, that had a range up to 1,800 m (2,000 yd) and accuracy for both was poor.

Due to its limited range, the launchers were vulnerable to counter-battery fire and their poor accuracy made them more useful in siege operations than in defense.
