What LCS Was Supposed to Be?

Let's say a group of ship designers liked the original "streetfighter" idea, had a history of corvettes and small missile boats - but as most sane people do, just shook their head at the the US Navy's LCS and said, "Well, let's not do that?"

What would they come up with? Perhaps something like what Russia seems to have sketched out;

The vessel is expect to displace just 1,500 tons with a top speed of 35 knots.

Based on the various illustration available, it seems like this "Russian LCS" Trimaran could be fitted with:
A-192 130-mm main gun
UKSK VLS cells and/or Redut VLS cells
Paket-NK torpedoes
AK-630M-2 "Duet" CIWS
PK-10 decoy launchers

Furke radar
Mini-Poliment radar(from 20385)
"Zarya-2" Hull Sonar, "Vinietka" VDS
"Puma" 5P-10 artillery radar
Spot for helicopter Ka-27 type in underdeck hangar

1,500 tons with a 5.1" gun, torps, and multi-use VLS?

Yes, they learned their lessons well. They, like us, may make a dog's breakfast out of a good idea - but let's give them a chance to fail.
