1mother,
Just to let you know there is no real cargo configuration on the SH60 B, just prior to the "foward" bulk head there to avionics (mission)racks, the left rack consist of the senso operator station and sensor avionics and the right side consist of the avionics only. Also the avionics racks are covered with sound proofing, most of the time, so you don't really see the mission racks. There is a aprox. 2 feet wide walking area between the mission racks that leads up to the cockpit, which is actually open, except for the lower center console in the cockpit. You can not remove these mission racks from the helicopter or it will greatly effects the helicopter. Just aft of the senso station seat is a sonobuoy launcher system and RAST recovery system just to the right on the deck. These items can be remove with without affecting the flight of the helicopter. I hope this helps you.
