The Kerbodyne KE-1 "Mastodon" Liquid Fuel Engine is a powerful size large engine appropriate for first stages.

Usage

The Mastodon has the second-highest thrust-to-weight ratio of any liquid fuel engine in the game, trailing only the "Twin-Boar", which has the highest after subtracting away the integrated fuel tank.

The Mastodon has 90%-93% of the thrust of the Mainsail, but only 83% of the Mainsail's weight and 62% of its cost. So it is often an effective replacement for the Mainsail.

Because the Mastodon can be independently mounted, clusters of this engine are an ideal way to lift extremely heavy payloads, such as 5-9 mounted on the Kerbodyne Engine Cluster Adapter Tank.

Product description

Considered to be the behemoth of rocket technology, this propulsion system is the pinnacle of power.
