While announcing six of these all at the same time in say 1934 or 1935 will certainly be a red flag to John Bull, maybe they could be staggered in pairs. If the last pair is laid down by mid-1938, the British by then are almost starting to react anyway, and this final pair might be ready by mid-1941. Or heck, make that 1939 to 1942. After all, it's not as if the real counterparts were ready in September 1939.
Or maybe make just four of those. Even if you forego the additional two, for what the Bismarck and Tirpitz achieved you are probably just OK anyway, and you've spared money, steel and time.
OK, given the average quality of the posting in this thread, I think I'll try to put down something more productive along these lines.
The requirements are to do as much as possible in this category of naval construction, and at the same time not to provoke Britain (and other powers) too much; at least, not until it's too late anyway.
The items in the list are construction projects and PR/diplomatic initiatives
1929-1935 Build the 3 Deutschland-class ships, hastening the commissioning of the last one a year.
1933-1935 Leak stories according to which these ships undergo embarrassing failures; they are not very seaworthy, their engines break down etc. (no need for excessive exaggerations here). The first one seems to be very disaster-prone.
1935 Lay down the first two Scharnhorst-class ships.
1935 Do not reject all Versailles disarmament clauses openly. Propose a naval conference. Drag diplomatic feet until next year.
1936 Sign AGNA a year later but basically with the same clauses. The only exception is that you undertake a commitment to turn Deutschland into a training ship as soon as Scharnhorst is ready. You can justify this by pointing out that the Deutschland (not the least because of the name) is nothing but a big embarrassment.
Now you have some 190,000 tons available for anything larger than a cruiser. You insist that the existing Deutschland class ships are 11,000 tons (they are bigger, but not officially). The Scharnhorst will count only as a replacement of the Deutschland, so you have an 11,000-ton freebie.
Your official program in 1936 amounts to:
3 Deutschland class, in service, total 33,000;
2 Scharnhorst class, in construction, total 62,000;
Grand total 95,000, you're more than OK.
In 1937, you lay down two more Scharnhorsts. These can't be ready before 1940, but it's not so bad. Your official program now amounts to a total of 157,000. It's enough to make British admirals very unhappy, but you're still within the AGNA limitations and far from making headlines in London.
In 1938, you lay down one more Scharnhorst (will be ready in early 1941) and downgrade the Deutschland as a training ship; you're doing it earlier than you promised, which should give some positive coverage. Your total is now 177,000. More and more worrisome, you are in the headlines now, but still within treaty limitations.
In 1939, you lay down the last Scharnhorst (will be ready in 1942) and countermand the status of the Deutschland, turning it to active duty again, your total is now 219,000 tons but you don't care any more. By mid 1939, 3 Deutschlands and 2 Scharnhorsts will be in service.
