~550 Kg payload to 200 km LEO, after accounting for ~180 kg for navigation and control avionics and batteries.
With following Agni configuration:
Payload = 750.0 Kg, Number of Stages = 4, Simulation Time Granularity = 0.100 Second
Launch Direction = 50 degrees-North, Launch Latitude = 22.00 degrees

this is more or less agni V, isnt it ? in the start-1 case, the small fourth stage had abt 2 tons propellant. maybe more. maybe that makes abig difference. Have you compared this with the israeli Shavit-2? They claim 300kg payload to leo with 143 degree inclination.....with a launch weight of 30 tons approx. westill have to catch up in payload/weight terms. still , 550 kg to 200 km leo would mean 800+ kg to a full icbm range. remember reading that the 1970s valiant project aimed for 500 kg to 8000 km...that too with a launh mass of 85 tons or so...
