Kapal tempur Jerman Bismarck
Proyek ini dimulai pada Januari 1939 dengan perhitungan perang melawan Inggris baru akan dapat berkobar pada 1945. Rencana Z itu antara lain membangun kapal perang berukuran 56.000 ton yakni Bismarck dan Tirpitz yang beratnya 42.000 ton, tiga kapal perang berukuran 31.000 ton (Deutschland, Admiral Scheer dan Graf Spee) yang lazim disebut kapal perang kantong (pocket battleship,Panzerschiff), dua kapal pengangkut pesawat (salah satunya adalah Graf Zeppelin), lima kapal jelajah berat (Hipper, Blucher, Prinz Eugen, Seydlitz dan Lutzow). Di samping itu ada pula 44 kapal jelajah ringan, 68 perusak, 90 kapal torpedo dan 249 kapal selam yang terkenal sebagai U-Boot. Hitler berjanji kepada Raeder bahwa Jerman dalam waktu singkat tidak akan berperang dengan Inggris.
Panzer VIII Maus
On 1 May a wooden model of the "Maus", a tank project of Porsche and Krupp, was shown to Hitler. It was intended to mount a 150 mm gun. The total weight of the tank was supposed to reach 175 tons. It should be considered that after the design changes on Hitler's instructions the tank will weigh 200 tons. The model didn't have a single machine gun for close combat, and for this reason I had to reject it. It had the same design flaw that made the Elefant unsuitable for close combat. In the end, the tank will inevitably have to wage a close combat since it operates in cooperation with the infantry. An intense debate started, and except for me, all of the present found the "Maus" magnificent. It was promising to be exactly that, a "giant".[1]
