The Sea Panther

The Sea Panther is a twin jet amphibious flying boat aircraft. It is being developed by Pepin Aero, LLC in Greenville, Maine USA. The Sea Panther will cruise at 420 kts at 38K feet yet will stall at 60 kts allowing water operation using hydrofoils. It will be the fastest amphibian in the world.

Pepin Aero, LLC is collaborating with G2 Systems Design of Wichita, KS to develop the Sea Panther.  Preliminary design includes trade studies to establish the outer surface shape, engine selection, and validation of target performance. Two areas of technical challenge include the 7:1ratio of cruise speed to stall speed and water operation using hydrofoils. The preliminary design for the four place version is complete while the air taxi version design is ongoing. Structural design of both versions of the Sea Panther is planned shortly.

Possible missions for the Sea Panther include military special operations, medevac, bird dog for fire fighting tankers, coastal patrol, air taxi for island resorts, and other amphibious requirements.   Our case study provides details of medevac scenarios.  Details of other missions will follow.   

• 1,200 nautical mile range enabling direct-to-care transport 
• Amphibious operations: water, gravel, and runway access 
• Up to 40% cost reduction + 3–5x faster response times
