Two different names for one GEV, man these Russians need to improve their project naming systems
the TTS-IS (also know as the HCA-LB) is a project by TsAGI for a very large wing-in-ground-effect, lifting-body, amphibious cargo aircraft capable of flying above water, ice, or ground to reduce drag, it is designed to be able to leave ground effect to take off and land at conventional airports as well as on water.
Also called Heavy Cargo Aircraft with Lifting Body (HCA-LB), the aircraft is the result of work beginning in 2014 as a proposal by TsAGI under a Russian government contract. The HCA-LB was formally introduced to the public in January 2017, and it began wind tunnel testing in 2018. The aircraft is targeting for a service entry in the 2030s or later. It carries twenty-foot equivalent units (TEUs) in four rows of six containers side by side on the port and starboard parts of the aircraft, for a total capacity of 48 TEUs. The two cargo areas are separated by an insulated fuel tank stretching the length of the center fuselage, holding cryogenic liquefied natural gas (LNG). The HCA-LB is nominally powered by a row of four turboprop engines positioned behind the cargo, atop the fuselage in a pusher configuration. The HCA-LB has a pi-tail empennage, with the twin vertical tails extending from near the back outer corners of the cargo sections.
General characteristics
Crew: 9
Capacity: 500,000 kg (1,102,311 lb) payload
Length: 75 m (246 ft 1 in)
Wingspan: 95 m (311 ft 8 in)
Aspect ratio: 3 to 4
Gross weight: 1,000,000 kg (2,204,623 lb)
Performance
Cruise speed: 450–550 km/h (280–340 mph, 240–300 kn)
Range: 6,000 km (3,700 mi, 3,200 nmi)
Service ceiling: 3,000 m (9,800 ft)
Lift-to-drag: 25-30 in ground effect

SPECIAL MECHANIC
Due to being a class B ground effect vehicle (capable of leaving ground effect) instead of getting a range boost at max altitude it will gain the range boost when flying 5-20m above ground level
