The Knarr Fully Reusable Heavy-Lift Launch vehicle, taking its name from the ancient Viking merchant ships, is being developed to support the Asgard Munar settlement program. Knarr manages to make the Asgard base affordable, being capable of getting up to 40T to LKO in FRTLS (Full Return to Launch Site) and 60T to LKO with a droneship landing, at only 30k funds. Making the price only around .6 funds/ kg. All while also having a 4m payload fairing, allowing it to carry large landers and surface bases.
First stage reuse has been demonstrated on many vehicles to date, but Knarr is the first of its kind to use a state-of-the-art distributed thrust arrangement for its second stage. 14 Aerospike engines make up the ring surrounding the heatshield, and provide a minimum TWR greater than 1.5.
UPDATE 11/7/2023: Replaced ring of 18 Thuds with a ring of 14 aerospikes to improve second stage performance by 10-12%. Twitch engines were added for SAS controlled gimbal, and KAL controllers manage differential thrust for larger manuevers.
