Bigger versions of the N-156 studies. Best I could do from a photocopy- they are tiny, white on blue.



Excellent quality.

Could PD-2706 depict the configuration of the T-tail, naval fighter that originally carried the N-156 designation?

Last one - I seem to have missed 1 out, will check.

[edit - I didn't post the N-102 Fang drawing as better ones are available]

I've never heard of a V-tailed version of the Fang. Any other particulars on that design, Scott?

What ya see is what I got. It comes from page 173 of... some book or other. Photocopied back in the days when I was too poor to photocopy the books title page, and too lazy to scribble the title down.

And so the endless circle of life comes to an end, meaningless and grim. Why did they live, and why did they die? No reason. Two hundred million years of evolution snuffed out, for in the end Nature is horrific and teaches us nothing

Is anybody able to identify this Northrop light-weight fighter design from the mid-1950s?

SOURCE: Stevenson: The Pentagon Paradox (page 71)
CAPTION: During the mid-1950s, Northrop Corporation developed some proposals for lightweight fighters specifically designed to fly off the escort (CVE) carriers.

It's the Northrop N-156: two GE SJ-110s (J-85), Mach 2. It was, through the slightly modified N-156N, the forebear of the T-38 Talon (N-156T).

Wow!

Thanks for the confirmation that the PD-2706 is indeed the lightweight fighter proposal made to the Navy, a year before the N-156 configuration was proposed to the USAF.

Does the Mini-Docavia have an entry on the N-285B?

Jerry Scutts confirms it in "Northrop F-5/F-20"

The light naval fighter study depicted above was N-165NN, emerging as PD-2706 in November 1955. It had a T-tail, full span trailing edge flaps and provision for a tractor type landing gear.

I just realised that the odd looking 3 view in the Jerry Scutts book, P11 is actually the N-156F posted earlier- with the addition of wingtip missiles.  It has no caption in the book, I assumed it was a badly drawn F-5A. Will post later.

Other F-5 projects:

N-156C
Camera nose, swappable for the standard nose, without losing gun armament

N-156D
Carrier version. Larger wing, more fuel, greater payload, strengthened arrestor gear. Offered in 1965 to the Australian Navy as N-285B (also offered to USN)

N-156E
Version using GE CF-700 aft fan engines, 6,800lb thrust.

N-156C did materialize as a RF-5A conversion (I seem to remember one of the F-5A kits out there  has the option).  N-285B was a development of the N-156D to meet USN objections to the original N-156D design; in addition to the larger wing et al., it included a stepped cockpit arrangement in the two-seat version.  I've seen the brochure once, if I could've copied it I would've, but I was in a very secure environment at the time and couldn't.
