Russian Oscar II in 1/96 scale

The Oscar-class nuclear-powered cruise missile attack submarine, which displaces more than 18,000 tons when under water, is one of Russia's largest and most capable submarines. As with earlier cruise-missile submarine, the Oscar was designed primarily to attack American aircraft carrier battle groups.

As with other Russian submarines, the Oscar features a double hull -- and inner pressure hull and an outer hydrodynamic hull, with eight inches of rubber between them to muffle sounds. American submarines have a single pressure hull, with additional hydrodynamic fairings, such as the cap that encloses the bow sonar dome. The 3.5 meter separation between the inner and outer hulls on the Oscar provides significant reserve buoyancy, and improved survivability against conventional torpedoes.

These large submarines are said to be slow to dive and maneuver, though they are credited with a submerged speed of about 30 knots - sufficient to keep pace with their targets. The improved Oscar II is about 10 meters longer than the Oscar I, possibly making room for a quieter propulsion system, and feature upgraded electronic systems. The Oscar II is also characterized by a substantially enlarged fin, which should improve underwater maneuverability, as well as the substitution of the Oscar-I's four-bladed propeller with a [presumably] quieter seven-blade propeller.

I have received this wonderful hull from a fellow SubCommittee member. The castings are very crisp and clear, though the hull layup is quite thin. All of the appendages are very well cast in resin, and there are blueprints included for the buildup as well.

I have a SubDriver with twin screws that I'll be using for the sake of simplicity, though I do happen to have an extra Engel TAE dive controller and a pair of piston tanks that I could use. I haven't decided which way to go, yet.

For now, I'll think on it and how I want to proceed.

These photos were taken by the Seller before it was shipped to me:

Just an update! This project actually sold about a year ago, uncompleted, but I'll keep these up here for future reference for anyone interested enough to look!
