軌道炮彈目標造價是一發 25000 美金，一枚戰斧 Blk 4 要 159 萬，，一枚魚叉 Blk 2 要 120 萬，一枚 SLAM-ER 要 50 萬，JSOW 由 28.2~71.9 萬不等
目前的技術能造出全功率四百發壽命的磁軌，如果冷卻容許無間斷開火，射速 6 rds/min 能使用 66.7 分鐘，離目標一千發還有相當距離
試射的炮彈暫時是無導引，指令導引會面對高音速下 RF 訊號收發難題，而今年初海軍發出的自導元件 RFP 規格非常嚴苛...
40000G 要求不難達到，因爲測試曾打出 60000G，但是可能代表得先部署低功率版本
"The package must fit within the mass (< 2 kg), diameter (< 40 mm outer diameter), and volume (200 cm3) constraints of the projectile and do so without altering the center of gravity. It should also be able to survive accelerations of at least 20,000 g (threshold) / 40,000 g (objective) in all axes, high electromagnetic fields (E > 5,000 V/m, B > 2 T), and surface temperatures of > 800 deg C. The package should be able to operate in the presence of any plasma that may form in the bore or at the muzzle exit and must also be radiation hardened due to exo-atmospheric flight. Total power consumption must be less than 8 watts (threshold) / 5 watts (objective) and the battery life must be at least 5 minutes (from initial launch) to enable operation during the entire engagement. In order to be affordable, the production cost per projectile must be as low as possible, with a goal of less than $1,000 per unit."
