More information

The WB-57 can carry up to 4400 kg of payload (including the empty weights of the pallets, spearpods and superpods). Refer to the table below for maximum gross weight limits for the various payload integration locations. The aircraft is sensitive to Center of Gravity (CG) location, so ballast may need to be added (primarily in the nose), which subtracts from overall payload capacity.

Payload Integration Location --- Payload (Maximum) --- Empty Weight
3-foot unpressurized Pallet ------------ 454 kg ----------------- ~75 kg
3-foot pressurized Pallet ---------------- 454 kg ---------- ~181 kg (estimated)
6-foot unpressurized Pallet ------------ 907 kg ----------------- ~112 kg
6-foot pressurized Pallet ---------------- 907 kg ----------------- ~318 kg (estimated)
Nose Cone ------------------------ 433 kg ----------------- ~105 kg
Aft Fuselage ------------ CG dependent, contact WB-57 Program Office
Spearpod Forebody ------------------ 168 kg ------------------- ~41 kg
Superpod ------------ Pylon and Forebody: 644 kg - Pylon: ~230 kg
-------------------------------------------- Forebody: 181 kg ----- Forebody: ~64 kg
Winghatch --------------------------- 29 kg ------------------ ~2.5 kg
