One of the most important advantages of the Sikorsky HH-52 Seaguard aircraft is their ability to land on water, which in some cases is indispensable, especially if we take into account the fact that the current model is in demand among the coast guards of many countries. In addition, the Sikorsky HH-52 Seaguard aircraft has a sufficiently long flight range, and can carry up to 1460 kilograms of payload on board.

Among other things, model helicopters Sikorsky HH-52 Seaguard and used as a means of transport, as a patrol aircraft, and are used for search and rescue operations.

Helicopter Sikorsky HH-52 Seaguard, as it is not used for the carriage on its occupants, however, if necessary, can accommodate up to 12 people, including 3 9 crew members and passengers. The aircraft is also suitable for transporting on board his small loads, the only condition which is to comply with the rules on not exceeding the maximum take-off weight of the aircraft, constituting 3764 kilos.

The Sikorsky HH-52 Seaguard aircraft, also known as the Sikorsky S-62 Seaguard, is equipped with a gas turbine power plant consisting of one General Electric T58-GE-8 aircraft engine, the power of which is 1250 hp. When using this aircraft engine, the Sikorsky HH-52 Seaguard helicopter can accelerate to the maximum speed of 175 km / h, which is one of the negative moments of operation of this aircraft. Nevertheless, depending on the modification, the helicopter can also be equipped with other power units, which in some cases affects the speed characteristics of the aircraft.
