Super Thunder Blade/Stage 1

Stage
Stage 1 takes place in a straight-line city environment, with tanks on the streets and planes flying overhead. After a halt, the stage's mid-level boss, an oversized tank, appears; destroy the turrets on its sides and main gun to clear it. From there, the stage switches to an overhead perspective as it flies over an aircraft carrier. Avoid the cannons on the carrier's floor and destroy the grounded planes for more points.

Mid-boss
Maneater Sub-Commander (TM-91B2) in western manual or MANEATER [TM-91B2] in japanese manual. Exclusive to Super Thunder Blade. A large tank with three missile launchers and a High-Power Mason Cannon. Easy to avoid by circle motion.

Boss
Seaminer Commander (CVA-65) in western manual or SEAMINER [CVA-65] in japanese manual. It's actually a different kind of ship than the one in Thunder Blade, being aircraft carrier. Thus much wider, carries aircraft and missile launcher are placed on the sides.
