Project 2038.0: Steregushchy Corvette

Hey thanx Garry . So , just to be clear are the 76 mm guns been upgraded to 100mm , 130 mm or are they replacing the 76mm with news 100 mm , 130 mm guns ?

The corvettes that are the subject of this thread would have gotten an armament in Soviet times of a single 76mm gun and probably either two 30mm gatling turrets or perhaps a single turret and an SA-N-4 naval OSA equivalent and perhaps 4-6 large anti ship missiles like SS-N-22 Moskit.

Fitting a 100mm gun would have been out of the question because of the weight of the 100mm guns.

The Corvettes being made now will be fitted with 100mm guns that weigh about the same as the old 76mm gun but with a much heavier shell fired over much greater range, plus much more heavily armed in terms of other weapons and choices.

For instance the single UKSK launcher will allow it to carry 8 Onyx supersonic anti ship missiles, but could just as easily carry anti submarine missiles that deliver torpedoes to targets 40km away at mach 2.5, or land attack cruise missiles able to hit targets 2,500km away or any combination of these weapons.

They have developed new light weight 100mm and 130mm guns that are the weight of 76mm and 100mm guns respectively.

The new 152mm gun was developed with the Army and in the army it is entering service as the Koalition. It has an effective range of about 70km and has Glonass/laser guidance to allow precision targeting.

Generally for production batches the cost is lower over lead ship but here is exactly the opposite.

That really only applies to a shipyard ready for production.

In this case the shipyard was in poor condition and would scramble to build a ship properly.

Getting a second order wont help that much unless there is a profit padded in there to pay for infrastructure.
Very simply when you are paid to build something you work out materials and labour costs and use any profits to reinvest into the shipyard with new equipment, extra training and personnel.

When you are tragically underfunded you take the first money you are paid and try to pay off some debt so the subcontractors you need to build components will continue to work with you. You scrimp and scrape parts together at the lowest cost so you can invest more of the money into the infrastructure so future contracts can be tendered for.

the dramatic increase in price is likely largely for infrastructure and tooling and training costs which should lead to improved production performance without the scrimping and lead to the costs going down later and production speed increasing.

In that second video you can see the tube for the missile does not take up the entire area for the "tube" under the hatch.
