The Mjolnir/V variant was developed and tested at a UNSC Low/Zero Gravity Testing Facility facility in Lister, Aigburth on Ganymede, integrating feedback gathered from the Summa Deep Space Incident. The V variant for the Mark IV still required a T-PACK for maneuvering in zero gravity. The Mark VI Mjolnir/V variant focuses on increasing exo-atmospheric endurance and improving mobility in zero gravity without the original use of back thrusters.
