Lindemann has another 2 months of intensive training before the mission, and this is one month before PoW even gets her last turret(s) accepted.
No,
Lindemann completed the curtailed version of AVKS on April 2nd (or 1st), after which he had to do overhauls, repairs, and remedy work to the battleship. From the warlog, it would seem that approx. 3 to 4 weeks were used for training in the Bay of Danzig, in the time period Apr 1st to May 18th.
The Baron is a useful source for Bismarck's working up exercises. He states:
The second half of November was spent in more tests of the Bismarck and her engines. The only thing new was that gunnery drill was added to the routine. Not only were the brand-new guns tested for steadiness, the smooth working of their mechanisms, ballistic performance, and accuracy, but the resistance of the ship’s components to recoil was also tested. Practice firings served to train the gunlayers in the best way of keeping on target. These drills could be carried out satisfactorily at close range with 8.8- or 5-centimeter sub-caliber guns inserted into the barrels of the heavy and medium guns. Because the shells and powder charges used were relatively light, this kind of firing was economical. At the same time, it gave the gunnery officers practice in fire control. Full-caliber firing! Unforgettable was the day the Bismarck’s heavy guns fired their first full salvo. How far, how violently would the recoil cause the ship to heel over, how quickly would she right herself? Below, in the engine rooms, where steam pressure was fifty-six times that of the atmosphere, the seconds passed slowly. A single crack in the main steam line caused by the shock of firing could result in the death of everyone in the engine room. Boom! The ship seemed to be abruptly jarred sideways, a few loose objects came adrift, a few light bulbs shattered, but that was all. Topside and in the control centers, it was quite different. Up there, the sideways movement was scarcely noticeable...
At the end of her trials, the ship was scheduled to return to Blohm &. Voss in Hamburg so that the yard could give her the “finishing touches” it had not been able to complete by September. On 5 December, therefore, the Bismarck departed Rügen under escort of Sperrbrecher 6 and steamed for Kiel. Passage of the canal again took two days, and on 9 December we were back in Hamburg.
So unlike PoW, Bismarck was conducting full calibre shoots 7 months prior to combat. Also unlike PoW Bismarck was able to return to the builders for adjustment and repair of defects uncovered in training:
The final commissioning draft, which included
350 ordinary seamen and boys -- all handicapped by
the bare minimum of training - arrived on 1 March.
A week later King George VI toured the battleship and
inspected the ship's company drawn up in divisions
on the quarterdeck.
Such was the haste to bring the ship to opera-
tlonal status, that Prince of Wales, in company with
the battlecruiser Hood. weighed and proceeded from
Rosyth, bound for Scapa, on 24 March, even though
she was still uncompleted. With her went the small
army of Cammell Laird and Vickers-Armstrongs
technicians and tradesmen. all working against the
clock.
Officially Prince of Wales is classified as being
completed on 31 March 1941. but this was only
achieved by waiving the vital watertight compart-
ment air tests. ventilation tests, and a thorough
testing of the bilge. ballast and fuel-oil systems. It
was a dangerous expedient. Full power trials com-
menced on 8 May and, compared with Bismarck
which made frequent returns to the shipbuilders to
iron out deficiencies that had occurred during her
eight month working-up period, the Admiralty, in
their race against time, afforded no such niceties for
Prince of Wales.
