Ju 188 G & H
One problem with the Ju 88 that carried into the 188 was the lack of internal room for bomb storage.
Both carried the majority of their bombload on the outside of the plane on racks under the wing, where it greatly affected performance.
This was to have been addressed in the G and H models, which extended the fuselage downward for more room with the addition of a wooden pannier.

This modification also left enough room at the tail to fit a manned turret in place of the C model's remote-control one.
However this system proved to be just as limited as the remote-control FA 15, being so small that only gunners could fit into it, and had basically no ability to escape in an emergency.
The RLM rejected the manned design and planned on mounting the FA 15 even if it were unreliable.
Oddly, the designs still had the nose area extended under the plane for a rear gunner, when this would no longer
be needed and its removal would have greatly cleaned up the lines of the plane.
With the Jumo 213s now being sent to fighter production, the Ju 188 G-2 was to use the BMW 801 only, with the reconnaissance conversion known as the Ju 188 H-2.
Neither entered production before the war ended.

Ju 188R
In the summer of 1944, three E models were modified as [Vous devez être inscrit et connecté pour voir ce lien] with the addition of radar and either four 20 mm
MG 151/20s or two 30 mm (1.18 in) [Vous devez être inscrit et connecté pour voir ce lien] in the nose.
However, the added visibility of the 188 was not useful in the night role, and because the added drag of the radar washed out any speed difference, the Ju 188 R-0 was not ordered.

High-altitude versions
In 1943, it was planned to upgrade the entire lineup with even more wing area and a pressurized cockpit for high-altitude work.
A single basic airframe would be offered in three versions, the Ju 188J [Vous devez être inscrit et connecté pour voir ce lien], Ju 188K bomber, and the Ju
188L reconnaissance version.
All three did away with the under-slung gunner's compartment, leading to a cleaner nose profile, and the bomber and
recce versions mounted their loads in a long pannier under the middle of the plane instead of the deeper fuselage of the G and H models.

Simpler versions of these with no defensive armament and even longer wings became the Ju 188S fighter and Ju 188T intruder.
With Jumo 213E-1 engines 2,050 PS (1,510 kW, 2,020 hp) at take-off and 1,690 PS (1,240 kW, 1,670 hp) at 9,500 m (31,400 ft), the Ju 188T could reach 700 km/h (440 mph).
Operating at this altitude, the Ju 188S could carry only 800 kg (1,760 lb) of bombs.
Before any of these could start production, the entire lineup was renamed the [Vous devez être inscrit et connecté pour voir ce lien], the vastly improved performance warranting this change in name.
