Carrier Air Wing (U.S. navy 901009 etc)

Carrier Air Wing, known in Japan as U.S. Navy, is a side-scrolling shooter that Capcom dropped into arcades back in 1990. It's the spiritual successor to U.N. Squadron, built on similar bones but with a fresh coat of paint. If you spent quarters on that earlier game, this one feels like a familiar friend with new tricks. The arcade boards hit operators worldwide that year, though a planned release on Capcom's own Power System Changer never made it past the promo shots.

You pilot a carrier-based fighter jet through horizontally scrolling stages, blasting enemy aircraft and ground targets. The screen scrolls automatically, so you focus on dodging bullets and lining up shots. Pickups drop from destroyed enemies, giving you weapon upgrades and extra firepower. Each level ends with a tough boss, usually a massive warship or a giant mech. The game does not mess around with complex controls - move, shoot, and use a secondary attack when you have a special weapon stocked.

For a retro shooter fan, Carrier Air Wing holds up well. It captures that tight Capcom arcade feel where every hit and dodge matters. The graphical detail and sound design are solid for the era, and the difficulty curve keeps you on your toes without being cruel. It won't dethrone classics like 1942, but it nails the side-scrolling formula with enough personality to deserve a playthrough today, especially if you already enjoy U.N. Squadron.
