Your selected aircraft are compared in side-by-side arrangement below. You can always go back and Compare any two aircraft in our database.
Notes: Some entries contain '0', 'not available', or an 'NA' value. This is more common with conceptual, experimental, and x-plane designs. Rotary-wing system (i.e. helicopters) values include main rotor diameter as part of width/wingspan measurement. UAV entries may display crew values as '0', not taking into account ground-based controllers.
Sikorsky SH-3D Sea King Ship-based Anti-Submarine Warfare (ASW) Helicopter
NOTES: Shapes below depict aircraft from wingtip-to-wingtip / nose-to-tail assuming aircraft are being viewed from overhead perspective (the nose pointing towards the top of the screen). Helicopter widths include main rotor diameter. If any dimensional values are "NA" in the database then the presented shapes may appear skewed.
