The Sea Sparrow is an improved version of the Sparrow, featuring pontoons instead of landing skids, and a .50 caliber machine gun mounted below its fuselage. The pontoons make it possible for the Sea Sparrow to land on water without sinking.
In GTA Vice City, it is unlocked only by collecting 80 hidden packages and is not found anywhere else in the game.
In GTA San Andreas, the Sea Sparrow does not require unlocking, and can be found in certain places, although these locations are in regions that themselves need to be unlocked first.
In GTA Vice City Stories, the Sea Sparrow is used during the mission "The Colonel's Coke" and side-mission "Land Sea and Air Ace", but cannot be accessed outside of these missions. Because of its fully exposed engine, the Sea Sparrow is highly susceptible to gunfire.
It is, however, particularly useful for reaching Collectibles in GTA San Andreas, quick maneuvering, and shooting down other helicopters. Sea Sparrows are also useful in collecting oysters, since oysters are always located in water areas spread across the state.
- On GTA Vice City Stories, if you land the Sea Sparrow on the land and exit the vehicle, the helicopter will not be steady, unlike in GTA San Andreas and GTA Vice City.
- On GTA Vice City, if you park the Sea Sparrow inside the Pay 'n' Spray, it will emerge with wheels within the pontoons. The only repair garage big enough to accommodate a Sea Sparrow is the spray'n'go at Sunshine Autos, therefore it is unclear as to whether this glitch also features in Vice City Stories.
- On GTA Vice City, the Sea Sparrow's machine gun is like the sound of M-60 while in GTA Vice City Stories, it sounds like Micro-SMG or Minigun.
