I was searching about near future sci fi wepons which can have super long range (50000km+). It seams like no wepon fits the bill except missiles but i cant put a powerful enough engine on a missile.
So ablative propulsion was the only way. Tough sf had some impressive numbert on it. Ablative pellet propulsion can give isp as high as 50 million and also most of the focusing equipment is in the missile so you dont need huge mirrors on your ships.
I want my ships to have simple fiber lasers which can at as point defence and also propel the missiles.
So is it a practice wepon. How powerful lasers would you need for a good enough accleration (9g+).And what can be the best defence against such missiles.
