A model of the proposed 'Rescuer' Ekranoplan
The Soviet era's enigmatic wing-in-ground-effect (WIG) "ekranoplans" are set to make a comeback according to various Russian media reports. In particular, a massive 600 ton design that is intended to carry out resupply and search and rescue missions in the Arctic is said to be in development, with flight testing planned for sometime in 2022 or 2023.
The design, dubbed "Rescuer" is described as being be 305 feet long with a wingspan of 233 feet. Supposedly the craft's large size was decided upon due to its ability to operate in rougher sea states than smaller alternatives and because it can fly over long distances, described by Russian sources as "several thousand kilometers."
Naval expert Alexander Mozgovoy told the Russian news paper Izvestia that "ekranoplans are much more economical than airplanes, it will be possible to quickly move more cargo for a longer distance... If they are equippes with air-cushioned landing gear, they will be able to land even on snow ridges and flat ice."
Supposedly the giant "Rescuer" will feature a wingspan more than 100 feet wider than the one found on Caspian Sea Monster, which actually makes sense considering it's planned for the type to include traditional landing gear as well as its boat-shaped hull. This amphibian format would theoretically allow the aircraft to fly at higher altitudes, outside of ground effect, but with far less efficiency, while also giving it access to traditional airstrips. Many Soviet-era ekranoplans also had the goal of flying at higher altitudes as well as in their standard WIG mode.
The image of a "Rescuer" model (top of post) shown to Russian officials and industry personnel at an arms expo looks more like the smaller but similar Lun class Ekranoplan than the Caspian Sea Monster. It's possible that the Lun class design was sized up to meet certain requirements.
Russia is said to also be actively developing a medium-sized ekranoplan for use in the Caspian and Baltic seas. Dubbed the A-050 "Seagull," this WIG flying boat will have a displacement of approximately one tenth of the "Rescuer" design, or around 54 tons, and is slated to can carry 100 passengers. The interior of the 115 foot hybrid aircraft will look like an airliner and in total it can carry 18,000lbs.

Its intended uses include passenger service, cargo hauling, environmental monitoring, and working for the Russian Ministry of Emergency Situations. Most ekranoplans have the ability to access unimproved beach areas, which along with their high speed and heavy lifting ability, makes them pretty useful for disaster response.
Russia seems willing to spend big money is in the Arctic—a place Moscow views as a strategic stronghold that can be dominated early on for control of the region's energy reserves and emerging shipping routes.
With an expanding footprint in the frigid arctic, logistics are likely a major hurdle, and a craft like an ekranoplan may be an ideal long-term solution worth investing in. Outside of its stated humanitarian and support missions, the "Rescuer" is a fast ski-skimming target (around 300mph) that is impervious to submarine torpedoes or mine warfare. In essence, this is an access weapon as much as anything else.
