Okay, after about 1946/1947; the USN began to assign SCB numbers sequentially, starting with USS Norfolk (CLK/DL) as SCB-1; the USS Tang (SS) as SCB-2, etc.

By 1964, they switched to SCB numbering in blocks; e.g.

001-009 SCB-Cruisers
100 SCB-Carriers
200 SCB-Destroyers/Frigates
300 SCB-Submarines
400 SCB-Amphibious
500 SCB-Mine Warfare
600 SCB-Patrol
700 SCB-Auxilaries
800 SCB-Service Craft
900 SCB-Special Purpose

I may be able to fill in some of the gaps. However, I´m on holiday in Spain for the next week so you will have to wait about 10 days for the information.

All the best

I cobbled this together from various sources. The main ones were a middle 1960s edition of Ships and Aircraft of the US fleet and several Norman Friedman books. I have this in an Excel spreadsheet if anyone wants it.

Much of it edited 13.07.22 and 14.07.22 to make it easier to read. Plus a few of the gaps were filled.

And here is the later system from the same sources:
001-099 Cruisers​
001 AAW Modernisation of Cleveland class (This is a guess by me. I have no evidence to support it. However, it fits the pattern.)​
002 AAW Modernisation of Albany class​
002.66 Modernisation of CG-10 USS Albany in FY1966 conversion programme.​
002.67 Modernisation of CG-12 USS Columbus in the FY1967 conversion programme that was cancelled by the Navy.​
003 AAW Modernisation of Boston class​
100-199 Aircraft Carriers​
100 Studies for a CVS to replace the Essex class​
100.68 Version to be ordered in Fiscal Year 1968​
100.71 Version to be ordered in Fiscal Year 1971​
101 Major refit of the Midway class​
101.66 CVA-41 Midway's 1966-70 refit.​
According to Jane's 1974-75 it was projected to take 24 months and cost $88.0 million. It actually took 52 months and cost $202.3 million.​
101.68 CVA-42 Franklin D. Roosevelt's refit which was cancelled due to the time and cost overruns of Midway.​
Some sources say that it was SCB.103.68, but I think that's a typo.​
Some sources say that it was the designation of the austere refit which the ship had after SCB.101.68 was cancelled.​
101.70 CVA-43 Coral Sea's refit, which was cancelled due to the time and cost overruns of Midway. This is a guess. I have no evidence to support it.​
102 Nimitz class​
102.67 CVAN-68 Chester W. Nimitz, because she was ordered in Fiscal Year 1967.​
102.70 CVAN-69 Dwight D. Eisenhower, because she was ordered in Fiscal Year 1970.​
102.74 CVAN-70 Carl Vinson, because she was ordered in Fiscal Year 1974.​
103 See SCB.101.68.​
200-299 Destroyers​
200-219 Ocean Escorts (DE) which became Frigates (FF) in 1975​
200 Knox class ordered FY1965 onwards. The 16 ships ordered in FY1964 (DE-1052 to 1061) were SCB-199C.​
200.65 for the 16 FY1965 ships (DE-1062 to 1077)​
200.66 for the 10 FY1966 ships (DE-1078 to 1087)​
200.67 for the 10 FY1967 ships (DE-1088 to 1097)​
200.68 for the 10 FY1968 ships (DE-1098 to 1107) which were either cancelled or deferred.​
220-239 Destroyers (DD)​
222.66 ASW Modernisation of Forrest Sherman class​
223.67 DDG to be built in FY67 (Thanks to @A Tentative Fleet Plan in Post 6)​
224.xx The DX which became the Spruance class​
