Released 1998 · 298 pieces · 4 minifigures · Aquazone · Hydronauts

LEGO Hydro Search Sub (6180) was released in 1998 in the Aquazone · Hydronauts line, with 298 pieces and 4 minifigures. That makes it the 8th largest of the 35 Aquazone sets in the catalog. It was one of 11 Aquazone sets released that year (see them all). Released in 1998, 28 years ago, well past the two-to-three-year run most LEGO sets get, so it is almost certainly out of production.
