, the commander in chief of the Reichsmarine, pushed hard for the navy to resume design work, and in 1925, three new proposals were drafted. In addition to two sketches prepared in 1923, this totaled five different designs. Of the first two designs, "I/10" was a 32 knots (17.4 m/s) cruiser armed with eight 20.5 cm (8.1 in) guns while "II/10" was a 22 knots (12 m/s), heavily armored ship armed with four 38 cm (15 in). The three designs prepared in 1925—"II/30", "IV/30", and "V/30"—were armed with six 30 cm (11.8 in) guns with varying levels of armor protection. The Reichsmarine eventually opted for 28 cm (11 in) guns to avoid provoking the Allies and to ease pressures on the design staff.

The Reichsmarine held a conference to evaluate the designs in May 1925, though the results were inconclusive. Of particular importance was the continued French occupation of the Ruhr

 industrial area, which prevented Germany from quickly building large-caliber artillery. Nevertheless, the design staff prepared another set of designs, "I/35", a heavily armored ship with a single triple turret forward, and "VIII/30", a more lightly-armored ship with a pair of twin turrets. The Reichsmarine initially intended to lay down the first armored ship in 1926, but the design had not yet been finalized. The 1926 maneuvers informed the design staff that greater speed was desirable, and that year, a further two designs were submitted to Zenker. The initial design for Deutschland, ordered as "Panzerschiff A", was prepared in 1926 and finalized by 1928. Zenker announced on 11 June 1927 that the Navy had settled on one of several proposals for the new warships. The Reichsmarine had decided that the new ships would be armed with two triple turrets mounting 28 cm guns.

Political opposition to the new ships was significant. The Reichsmarine therefore decided to delay ordering the ship until after the Reichstag

The question over whether to build the new ships was a major issue in elections, particularly with the Social Democrats, who strongly opposed the new ships and campaigned with the slogan "Food not Panzerkreuzer." In May 1928, the elections were concluded and enough of a majority in favor of the new ships was elected; this included twelve seats won by Adolf Hitler

When the particulars of the design became known by the Allies, they attempted to prevent Germany from building them.

 tonnage. In doing so, this would effectively abrogate the clauses in the Treaty of Versailles that limited Germany's naval power. Britain and the United States favored making concessions to Germany, but France refused to allow any revisions to the Treaty of Versailles. Since the ships did not violate the terms of the Treaty, the Allies could not prevent Germany from building them after a negotiated settlement proved unattainable.

General characteristics

The three Deutschland class ships varied slightly in dimensions. All three ships were 181.7 metres (596.1 ft) long at the waterline, and as built, 186 m (610.2 ft) long overall. Deutschland and Admiral Scheer had clipper

The displacement of the three ships increased over the class. Standard displacement grew from 10600 LT for Deutschland to 11550 LT for Admiral Scheer and 12340 LT for Admiral Graf Spee. The ships' full load displacements were significantly higher, at 14290 LT for Deutschland, 13660 LT for Admiral Scheer, and 16020 LT for Admiral Graf Spee.

s built by MAN. The adoption of an all-diesel propulsion system was a radical innovation at the time and contributed to significant savings in weight. Each set was controlled by transmissions built by AG Vulcan. The engines were paired on two propeller shafts, which were attached to three-bladed screws that were 4.4 m (14.4 ft) in diameter. Deutschland was initially fitted with 3.7 m (12.1 ft) diameter screws, though they were replaced with the larger screws. The engines were rated at 54000 shp and a top speed of 26 knots (14.2 m/s). They did not meet the expected shaft-horsepower on trials, though they did exceed their design speeds. Deutschlands engines reached 48390 shp and 28 kn (15.2 m/s), and Admiral Scheers engines reached 52050 shp and 28.3 kn (15.4 m/s). Horsepower figures for Admiral Graf Spee are not recorded, though her top speed on trials was 29.5 kn (16.1 m/s).

Deutschland could carry up to 2750 MT (2,706.6 LT) of fuel oil; this enabled a maximum range of 17400 nautical miles (32,224.8 km) at a speed of 13 kn (7.1 m/s). An increase in speed by one knot reduced the range slightly to 16600 kn (9,037 m/s). At a higher speed of 20 kn (10.9 m/s), the range fell to 10000 kn (5,444 m/s). Admiral Scheer carried 2410 MT (2,371.9 LT) and had a correspondingly shorter range of 9100 nmi (16,853.2 km) at 20 kn. Admiral Graf Spee stored 2500 MT (2,460.5 LT) of fuel, which enabled a range of 8900 nmi (16,482.8 km). Electricity was supplied by four electric motors powered by two diesel generators. Their total output was 2,160 kW for Deutschland, 2,800 kW for Admiral Scheer, and 3,360 kW for Admiral Graf Spee, all at 220 volt
