If I remember correctly, this was a K. Tank design
I remember to see a 3 view diagram in Flug revue ages ago. I have not seen this since then.
Nice to see this again. :) :) :)
Can I assume the same length than Marut? What do you thing ???

Yes ... bit I think that the configuration shown in the FR is a very provisorial (?) drawing including a lot of guess-work !

Actually I don't think that the HF-73 had two fins as all other side views do only show one. This two-fin mystery may be based on a drawing, the German Flug-Revue published at a very early stage of that project. ???

That picture is from page 23 of the Flug-Revue Issue November 1975.
The following picture is from the opposite page 22.

Hai I'm a new member, I'm interested to know about this fighter. Can you please mention the page number?

Welcome aborad Sarath,and a more Info from Jet & Prop;

HF-73, variations
of a subject

The Indo-Pakistani War of the
Year 1971 didn't just have the merits
of the tank design, rather
The weaknesses of the Su-7 "Fitter" used by India were also shown. A
Call for tenders from 1966 (Ground Attack Fighter, GAF)
of the Indian Air Force, with a twin-engine combat aircraft that carries a weapon load of 3600 kg over a distance
of 720 km is required
got new meaning.

In 1971, the ASA (Advanced
Strike Aircraft) renamed specification
to HAL, which in turn is Kurt Tank
switched on, who had by no means lost interest in his design
and now sign up for the program again
committed. Tank pushed for one
Cooperation between MBB and
HAL. In fact, a came about in 1972
MBB team led by
H.Autumn to Bangalore to do the installation
possibility of Rolls-Royce / Turbo
Union engine RB.199 34R (post
burner thrust 6810 kp), which is known
acting as a tornado engine to investigate.

The developed project HSS-73 (Hindustan: Supersonic; Strike) only possessed
still superficial resemblance to that
"Marut", that is, the plane that is called
HF-73 should go into production,
was a completely new design. Planning saw the construction of 6
Prototypes, a break cell and more
than 200 series aircraft before after
comprehensive studies a computational
Maximum speed of Mach 2 at 11,000 m and the initial climb rate at least 300 m / sec.
should be. With 2000 kg external loads
a range of 650 km was expected.

Ultimately, the program was abandoned for cost reasons. The HF-73 thus shared the fate of the
HF-24 Mk 3, which has only one engine
should be equipped, with the
RB.153, SNECMA Atar 09 K-50 resp.
SNECMA M 53 was intended.
