Claim 14:
15. An exterior shell for an armored cab having a longitudinal axis and a transverse axis comprising:
a right side panel extending parallel to the longitudinal axis;
a left side panel extending parallel to the longitudinal axis;
a rear panel extending parallel to the transverse axis; and
a cab lower surface extending between the right side panel and the left side panel, the cab lower surface comprising:
a right hull transitioning at a right inflection point to define an integral right front plane defining a forward facing surface of the right side frame, wherein the right front plane is convexly curved upwards,
a left transitioning at a left inflection point to define an integral left front plane defining a forward facing surface of the left side frame, wherein the left front plane is convexly curved upwards, and
a center tunnel extending along the longitudinal axis, the center tunnel having an exterior curvature with a variable radius as the center tunnel extends along the transverse axis of the exterior shell, wherein the center tunnel is configured to act as a pressure vessel in the event of an explosion beneath the armored cab.
