HISTORY
 Russian naval ingenuity has long demonstrated its ingenuity from novel tactics employed by Admiral Rozhestvensky at the Battle of Tsushima to the globally superior Gangut class of meh-naughts. These versatile little scamps serve many functions for the Russian Navy: tugboat, patrol craft, and occasionally modular power plants for the Admiral Kuznetsov. Unfortunately, little is known of their specific service. From what is known, they appear capable of floating, independent power, and utility, placing them well above many of their peers in the Russian navy. You go, little dudes! 
SHIPS 
All three of these tiny vessels are 3D printed with minimal assembly. I'm not even certain PE would greately benefit what are honestly well-designed little kits. Combrig independently printed fragile or tiny details, like life rafts, to preserve their ability to print properly. Hatches and bulkheads are well-detailed and print lines seem shockingly minimized. I'd kill to know what their print settings are, to be honest. I cannot effectively comment on their general dimensions, unfortunately. As mentioned above, data on these vessels appears scarce. Details, overall, appear in-scale for comparable Western peers. 

INSTRUCTIONS

CONCLUSIONS

These little tugs are impressive kits and show just how far 3D printed models/parts have come over the last few years. Any of these would make great additions to showing a realistic Admiral Kuznetsov at sea. If someone could 3D print a realistic smoke plume that would make American full size truck drivers rolling coal* turn red with envy, you'd have it made. 

* For the civilized world, "rolling coal" is when you want your diesel pickup truck look like it's outgassing like an early 1900's factory. 

Thank you to both Modelwarships and Combrig for this review sample!
