Just a quick note today. My friend and colleague Ilya Kramnik plots out four alternative designs for the new Russian destroyer currently in the works.
1) 7500-9000 tons, ~160 meters long, gas turbine propulsion, top speed of >30 knots
Equipped with 1x1x130mm gun, 2 CIWS complexes, 32 universal shipboard firing complexes (Kalibr/Oniks) and 64 Redut shipboard missiles, 2 Paket-NK anti-submarine torpedo systems, 2 helicopters
2) 9500-11500 tons, ~190 meters long, gas turbine propulsion, top speed of approximately 30 knots
Equipped with 1x2x130mm guns, 4 CIWS complexes, 48 universal shipboard firing complexes (Kalibr/Oniks) and 80 Redut shipboard missiles, 2 Paket-NK anti-submarine torpedo systems, 2 helicopters
3) 12,500-14,700 tons, ~200 meters long, either gas turbine or nuclear propulsion, top speed of approximately 30 knots
Equipped with 2x2x152mm guns, 4 CIWS complexes, 64 universal shipboard firing complexes (Kalibr/Oniks) and 80 Redut shipboard missiles, 2 Paket-NK anti-submarine torpedo systems, 2 helicopters
4) 13,000-15,200 tons, ~210 meters long, either gas turbine or nuclear propulsion, top speed of approximately 30 knots
Equipped with 1x2x152mm guns, 4 CIWS complexes, 16 universal shipboard firing complexes (Kalibr/Oniks) and 48 Redut shipboard missiles, 2 Paket-NK anti-submarine torpedo systems, 5 helicopters
All four versions would have the Sigma-E combat management system and Poliment active phased array radar. The largest of these options is pretty close to a cruiser, I suppose.
