So, let's begin with a little maths : Today, hydrogen and quantum tank are in Liters unit. As you can see in this picture for the Mercury : In 3.17, Astro services speak in SCU unit : If you divide Liters by SCU, you can find that 1SCU = 18 000L (4 850 840 / 269.48). This value is identical for Quantum fuel (so the MSR has 0.541 SCU of Quantum fuel) The Starfarer has 6 externals pods of 60SCU each (360SCU or 6 480 000 Liters). With the currently balance pass on PTU, the Hammerhead has now 15.1M Liters hydrogen tank or 842SCU (it's 6.9M or 386SCU in 3.16.1). I think you see the problem now. It's impossible to entirely refuel the HH despite the 6 MASSIVE external tank. In fact, you can only provide ~42% of fuel. And the best for last, the 60SCU pods can transfer fuel at 0.07SCU/s maximum rate, so you need 85 minutes to half fill the HH. Few examples with hydrogen capacity in SCU unit : 400i (297SCU) = 71min to refuel and 5 pods depleted MSR (269SCU) = 64min to refuel and 4.5 pods depleted 600i (133SCU) = 32min Redeemer (37SCU) = 9min Ares Ion/Inferno (25SCU) = 6min Cutlass Black (20SCU) = 5min Nomad (18SCU) = 4min --------------------------------------- EDIT : changes from PTU 3.17.08025815 Pod : GSX-RF : SCU:55 Flow Rate: 0.1 -> SCU:50 Flow Rate: 1.5 GSX-HP : SCU:65 Flow Rate: 0.01 -> SCU:70 Flow Rate: 0.9 CR-60: SCU:60 Flow Rate: 0.07 -> SCU:60 Flow Rate: 1.5 Fuel Nozzle : Norfield : Flow Rate: 0.08 Health: 150 -> Flow Rate: 0.3 Health: 500 Harkin : Flow Rate: 0.09 Health: 300 -> Flow Rate: 0.8 Health: 250 RN-7s : Flow Rate: 0.07 Health: 200 -> Flow Rate: 0.4 Health: 350 A step in the right direction ! Please, buff the pods capacity, GSX-HP should be 120SCU at min ! New time value with the fastest nozzle : 400i (297SCU) = 6min MSR (269SCU) = 5:30min 600i (133SCU) = 2:40min Redeemer (37SCU) = 46s Ares Ion/Inferno (25SCU) = 31s Cutlass Black (20SCU) = 25s Nomad (18SCU) = 22s Gladius (7.5SCU) = 10s
