I browsed the Useful Links pages in Site Feedback, and in the Supermarine one posted by Lark there were two "blank" pictures 718 supersonic Valiant, and 718 low level Valiant
I've tried the site search engine, with no results.
Does anyone have any info on what these are?
(The low level Valiant outline shown is NOT the B2)

I should have 'Googled' before posting.
there is a tiny bit at:
A "low level Valiant" design featured a fuselage stretch, short wings, and additional fuel carriage. A "supersonic Valiant" design featured a highly swept ...

Thanks. I thought I'd seen the supersonic Valiant before.

-718- was the type number given by Vickers
to the planned production variant of the Valiant B Mk.2.

The order for 17 aircraft was cancelled and replaced by additional B Mk.1's.

Eric B. Morgan in his already mentioned book gives the following specifications of the two Valiant's derivatives:

Low-altitude Bomber

Bomb-carrying capacity 10,000 lb (4,536 kg)
Max. speed Mach 0,85
Range 4,300 nm (7,964 km)
Cruise speed with drop tanks 521 kts (965 kph)
Cruise speed w/o drop tanks 566 kts (1,049 kph)
Span 81 ft (24.7 m)
Length 124 ft 6 in (37.9 m)
Wing area 2,150 sq.ft (200.0 sq.m)
Basic weight 99,200 lb (44,997 kg)
Max. weight 306,000 lb (138,802 kg)

Supersonic Bomber

Four reheated Convay 3s engines
Take-off weight 177,000 lb (80,287 kg)
Basic weight 102,000 lb (46,267 kg)
Max. speed at 30,000 ft (9,144 m) Mach 1,46
Max. speed at 36,000 ft (10,973 m) Mach 1,48
Span 85 ft (25.9 m)
Length 130 ft (39.6 m)
Wing are 2,000 sq.ft (186.0 sq.m)

What should be noticed is that, as Morgan puts it, "Both projects were the result of informal discussions between Vickers and the Air Staff and represented preliminary examinations without any detail design".

There are sketches of the both variants in the book, but as it was published by Midland Publishing, which is a subsidiary of Ian Allen, it would be wisely not to reproduce them here.

Best regards,
Piotr

BSP2 does mention Vickers 718 on page 216, making clear it refers to both the low-level and supersonic Valiant variants. Buttler forgot to mention the Type 718 designation when discussing the low-level and supersonic Valiant versions.

The Vickers Type 718 was the planned production Valiant B.Mk.2 and not related to the Low-Level and Supersonic design studies.

Couldn't find a dedicated Valiant thread, so hopefully this is a suitable place.

BSP2 mentions a dedicated PR Valiant to OR.279 with Conways and enlarged wings. Has a drawing or specifications for this version been published anywhere?

Is that the dedicated OR.279 aircraft? The caption refers to it as a conversion of a B.1, and neither modifications to the wings nor to the powerplant seem to be in evidence.
