BetterSRBs Description BetterSRBs modifies solid rocket boosters in Kerbal Space Program.  Although some new parts are added, this is really not a parts mod.  The purpose is to fix deficiencies in existing SRBs so that their performance and physical properties are internally consistent and closer to real life. SRBs continue to have mass ratios comparable to the stock game, but specific impulse has been increased to lifelike values.  Dry masses, fuel loads, and thrusts are computed
