Design and development
Due to the difficulties German interceptors were having when battling American [Vous devez être inscrit et connecté pour voir ce lien], and in light of rumors of new [Vous devez être inscrit et connecté pour voir ce lien] with better capabilities, the [Vous devez être inscrit et connecté pour voir ce lien] (German Air Ministry, or "RLM") requested proposals from both Focke-Wulf and Messerschmitt for a high-altitude interceptor.
Messerschmitt answered with the Bf 109H, and Focke-Wulf with the Fw 190 Raffat-1, or Ra-1, (fighter), Ra-2 (high-altitude fighter) and Ra-3 ([Vous devez être inscrit et connecté pour voir ce lien]),
which developed into the Fw 190 V20 (Ta 152A), V30 (Ta 152H) and V21 (Ta 152B)[Vous devez être inscrit et connecté pour voir ce lien], all based on the then successful Fw 190D-9 but with varying degrees of improvement.

The V20 used the same Jumo 213E engine as the Fw 190D-9, while the V21 used the DB 603E.
Neither of these offered any significant improvement over the Fw 190D-9, and so further development of the Ta 152A and B was cancelled.
The V21 airframe, however, was further modified as the V21/U1 and became the prototype for the Ta 152C.

Kurt Tank originally designed the Ta 152 using the [Vous devez être inscrit et connecté pour voir ce lien] engine as it offered better high-altitude performance and also a greater developmental potential.
The DB 603 had been used in the Fw 190C with many problems and was considered too difficult to implement in the Ta 152 by RLM officials. With this in mind, Tank focused his efforts on the [Vous devez être inscrit et connecté pour voir ce lien]E as the Ta 152H's power plant.
However, he insisted that the [Vous devez être inscrit et connecté pour voir ce lien] remained for the Ta 152C versions and as an option for later versions of the Ta 152H.

The Ta 152's [Vous devez être inscrit et connecté pour voir ce lien] was an extended version of the Fw 190D-9 fuselage with larger tail surfaces, and hydraulic rather than electrically-controlled [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien].
Due to the changes in the [Vous devez être inscrit et connecté pour voir ce lien] and overall balance, the nose was also lengthened.
[Vous devez être inscrit et connecté pour voir ce lien] was changed from the Fw 190's 10.51 m (34 ft 5 in) for both versions.
The H had a span of 14.44 m (48 ft 6 in) and the C a wing span of 11.00 m (36 ft 1 in).

Fuel capacity was 595 L (157 US gal) for the H-0 model, with the option of a 300 L (80 US gal) [Vous devez être inscrit et connecté pour voir ce lien] on the centerline.
The H-1 model carried an additional 454 L (120 US gal) of fuel in six unprotected bag tanks in the wings; typically, one of these tanks was used to hold the [Vous devez être inscrit et connecté pour voir ce lien] methanol-water mixture and another for [Vous devez être inscrit et connecté pour voir ce lien].
The H-1 could also carry a 300 L (80 US gal) underbelly drop tank.

Design for high-altitude performance
To reach higher altitudes, a [Vous devez être inscrit et connecté pour voir ce lien] was added to the H models.
The [Vous devez être inscrit et connecté pour voir ce lien] was sealed via a circular tube filled with foam rubber which was inflated by a compressed air bottle, while the engine compartment was also sealed from the cockpit with a foam rubber ring.
A Knorr 300/10 [Vous devez être inscrit et connecté pour voir ce lien] provided the pressure, maintaining the cockpit at .36 atmospheres (5.29 psi) above 8,000 m (26,250 ft).

To prevent fogging, the windscreen was of a double-pane style with a 6 mm (.32 in) thick outer pane and a 3 mm
(.118 in) inner pane with a 6 mm (.24 in) gap.
The gap was fitted with several silica-gel capsules to absorb any moisture forming between the panes.

The aircraft had an increased wingspan compared to the previous Fw 190 design, as a further accommodation towards better high-altitude performance.
Due to the war's impact on [Vous devez être inscrit et connecté pour voir ce lien] availability, the wing was built around two steel [Vous devez être inscrit et connecté pour voir ce lien], the front extending from just past the landing gear attachment points, and the rear spar spanning the entire wing.

The wing itself was designed with 3° of washout, from the root to the flap-[Vous devez être inscrit et connecté pour voir ce lien] junction, to prevent the ailerons from stalling before the center section of the wing.
This design allowed the pilot to maintain roll control during a stall and extreme flight envelope manoeuvres.

The Ta 152H boasted excellent high-altitude performance, using a [Vous devez être inscrit et connecté pour voir ce lien] engine
(a high-altitude version of the Jumo 213A/C used in the Fw 190D), a two-stage, three-speed [Vous devez être inscrit et connecté pour voir ce lien]
and the [Vous devez être inscrit et connecté pour voir ce lien] methanol-water mixture engine boost system.

Armament
The H-model had heavy armament to allow it to deal quickly with enemy aircraft.
It had three weapons firing through the propeller arc: one 30 mm (1.18 in) [Vous devez être inscrit et connecté pour voir ce lien] Motorkanone cannon centered
within the propeller hub and two 20 mm [Vous devez être inscrit et connecté pour voir ce lien] located in the wing roots.[Vous devez être inscrit et connecté pour voir ce lien]
