Rather poetic justice if they did.
Navy buying 'proven laser weapon' system for destroyers

The Navy is looking to buy a 60-150 kW high energy laser weapon system with an integrated counter intelligence, surveillance and reconnaissance laser for non-destructive dazzling capabilities against unmanned aerial vehicle-mounted sensors, according to a Federal Business Opportunities notice.

The High Energy Laser with Integrated Optical-dazzler and Surveillance project will "prioritize technical maturity and proven laser weapon concepts," the notice said.

The request for proposals seeks two test units to be delivered in fiscal year 2020, one of which is for an Arleigh Burke-class destroyer, DDG 51 Flight IIA. The second unit will be delivered to White Sands Missile Range in New Mexico before being transferred to Point Mugu in California, Naval Sea Systems Command spokeswoman Colleen O'Rourke wrote in a Aug. 15 statement to Inside the Navy.

Asked if the Navy will consider equipping Flight III with the laser weapon system, O'Rourke said the service is only targeting Flight IIA.

The RFP also includes options for an additional nine ship-based systems, O'Rourke added.

"The HELIOS Test Units shall include all necessary power, cooling, and processing hardware and software, along with all cables, interfaces, and displays necessary to operate and maintain the system on both a Land Based Test Facility and on a DDG 51 FLT IIA," the notice said.

HELIOS has $63.2 million budgeted for FY-18; $83.8 million for FY-19; $60.2 million for FY-20; $45.9 million for FY-21 and $30 million for FY-22, according to the Navy's budget justification documents.

Found by simply looking into the French aeroforum (,
but I think, it's well worth to be mentioned here, too.

They should just buy a handful of J20's and then build their own unlicensed version.

From Avions 101,

unfortunately the picture is not completed to know what was Dornier Do.22 took
from a "P" designation ?.

We can talk here about Fairey and its prototypes and Projects,and here is early
drawing to Fairey single seat fleet fighter to Spec. D of R.6 and some drawings
to Fairey Flycatcher,I don't know if some of them still Projects only or not ?.

MiG already has plenty of experience with such layout from 1.44 project. This sounds like scaled down variant of 1.44, tailored for next variant of rd-33 engines, so perhaps up to 100 kn thrust per engine?

While possible that AVIC had MiG's help for J20, it is also possible that roles may be reversed to an extent, and MiG collaborating with Chinese on that plane.

It would also mean it's the same weight class as Shenyang aircraft corporation's FC31 demonstrator plane. Russians better hurry then for export market, as SAC already has much of the plane developed.
An interesting distinction between the RB.153, RD-41 and F135 is that the first two used A/B in the hover. Also, by the looks of things, the RB.153 design put the burner in the final stage of the nozzle (hence its German name). How was that done on the Model 200 and the Yak-141?

As for the CL-84 in the background - GD owned Canadair until 1976.
Naval Projects / Re: never realized projects of Japanese destroyers ww2

Hi dear people I know that the Japanese navy was testing the IJN Shimakaze destroyer it stayed by one example, so she was one of a kind.
 Does somebody know there were more paper project destroyers or a further developed version of the IJN Shimakaze?

There are only a few projects.
Shimakaze (Project Number F-52) preliminary with 2x7 61cm torpedo tubes but the launchers deemed too large and heavy for the hull

The Super Shimakaze (Pre Project Number V-6) with somewhat slower speed due to standardised engines (68km/h rather 73) more AA guns compared to the original as launched, and 3 sextuple (6 barrel) torpedo tubes dated 1939

The Super Akizuki (Pre Project Number V-7) a modified Akizuki (Project Number F-51A (Akizuki), B (Fuyutsuki) and F-53 (Mitcitsuki)) with wider beam of 12 meters rather 11,2 meters but faster, 68km/h rather 61km/h and longer range of 14.800km rather 11.000km, heavier displacement of 3.030tons standard and 3.800tons full load otherwise the same armament as the Akizukis though a heavier torpedo armament might had been considered and dated 1941/42.

The Matsu and Tachibana (Project Numbers F-55A and B) would had originally a sextuple (6 barelled) 61cm torpedo tube, but due to production delays the simpler quad launchers were mounted.

These are all that I'm aware of. There should be at least one design which we lack information on and based on the number system:

F-48 - Asashio class (1934)
F-49 - Kagero class (1937)
F-50 - Yugumo class (1939)
F-51A - Akizuki class (1939)
F-51B - Fuyutsuki class (1941)
F-52 - Shimakaze class (1941)
F-53 - Michitsuki class (1942)
F-55A - Matsu class (1942)
F-55B - Tachibana class (1942)

The F-54 destroyer design is missing and if there are any post Matsu/Tachibana proposals.
