Jump Sail

From BattleTechWiki

A Jump Sail is a huge, totally black solar collector deployed by JumpShips. The sails are used to recharge the Kearny-Fuchida Drive on a JumpShip, which enables the JumpShip to traverse interstellar space in 30 light-year "jumps". The drive is very fragile and Jump Sails are the best way to slowly charge the drive. The sails themselves are between 800 and 1,300 meters in diameter.

Jump Sails are manufactured on the following planets:

Brand	Planet	Company
Forerunner I	Tamarind	Forerunner A.G.
Forerunner III	Tamarind	Forerunner A.G.
Forerunner IV	Tamarind	Forerunner A.G.
