Naval Projects / Re: Unbuilt Type-XXIX u-boat
« Last post by huckebein on Today at 06:42:08 am »
I have been working on a 3d model of this boat for some time.
I always interpreted the rear end as having a cort nozzle.
I guess this was wishful thinking.
This simplifies things a bit. :D

Go back even further for an actual example - the P-51 was originally designed by North American to a British requirement, and if only they had put a Merlin in it from the start (even a high-blown single-stage), it might have done wonders earlier than it did. And everyone forgets just how many B-29 bombers and F-86 fighters served with the RAF...

No need to play what-if, though it is fun; there are more than enough examples of WHEN.

FWIW, the B-29s were something of a failure in RAF service. Suffered from poor serviceability and were eventually returned to the US earlier than planned.

Hi,

in a report about Brazilian helicopter Projects; Engenharia de Helicópteros no Brasil: Introdução e Histórico,
there was an attack helicopter of 1985/87 called CTA Heliat or Heliatic,and a light helicopter called AlphaOne.

Missile Projects / Re: THAAD Development
« Last post by bring_it_on on Today at 06:22:22 am »
From the FY18 Budget Request :

Quote
$230.2 million for BMD Terminal Defense (PE 0603881C), THAAD development eff orts.
MDA will continue development of THAAD software upgrades such as implementation of
fl exible threat packages and defense planning, improved capability to engage SRBM, MRBM
and limited IRBM threats, and integration of the THAAD batt ery capability into the Integrated
Air and Missile Defense Batt le Command System (IBCS) planning process.

$36.2 million for Terminal Defense Testing (PE 0604876C). In FY 2018, THAAD will conduct
Flight Test Other-35 (FTX-35), a ballistic missile tracking test to prove THAAD software build
3.0 and test X86 AN/TPY-2 radar confi guration with a THAAD Batt ery. THAAD will participate
in Flight Test Other -36 (FTX-36), a ballistic missile tracking test, to demonstrate interoperability
between THAAD and PATRIOT. THAAD will also begin pre-mission planning for (FTO-03 E2)
to be executed in FY 2019.

$451.6 million to continue procurement of THAAD equipment, including 34 THAAD
interceptors in FY 2018. By the end of FY 2018, MDA will deliver 52 additional THAAD
interceptors to the U.S. Army, for a total of 210 interceptors delivered. MDA received an
incremental production decision in the 4th Quarter FY2016 for THAAD authorizing continued
production of at least 79 additional interceptors through FY 2020.

$78.8 million of Operations and Maintenance (O&M) funding to support the maintenance
and upkeep of all BMDS unique items of the fi elded THAAD batt eries as well as for all THAAD
training devices. In FY 2018 MDA will provide support to seven THAAD batt eries.

MDA requests $213.5 million to
develop advanced discrimination
algorithms for the AN/TPY-2,
Cobra Dane, Sea Based X-Band,
and the UEWR radars to
counter evolving threats. The
discrimination improvement
effort will develop and fi eld integrated Element capabilities to improve BMDS ability to
discriminate between lethal and non-lethal objects. In FY 2018, MDA will transition to production
of next generation Gallium Nitride (GaN) Transmit/Receive Integrated Multichannel Modules
(TRIMMs) to support the AN/TPY-2 sparing strategy and improve radar performance. $10 million
is budgeted for Gallium Nitride transition.

In FY 2018, MDA will increase Hypersonic Defense systems engineering activities, technology
demonstrations, and risk reduction, as a continuation of FY 2017 Department of Defense eff orts
to address weapons technologies to defeat advanced threats. Activities will include completion
of a Defense against Hypersonic Threats AoA, capability roadmap development, and initial
investment in sensor technology demonstrations and weapon concepts to address the advanced
threat. MDA will leverage existing sensors and ground infrastructure/Command and Control to quickly demonstrate and deploy a
three-phase limited contingency capability
to provide real-time warning over the
majority of the hypersonic threat profi le by
2019. MDA is requesting $75.3 million for
Hypersonic Defense activities in FY 2018,
(PE 0604181C).
MDA’s budget request puts a priority
on cybersecurity operations. MDA will
train, educate, develop and grow MDA’s
cybersecurity workforce to support
the mission....

Couldn't find a newer thread on the subject so posting here.

According to fy2018 budget documents (air force rdt&e volume 2 http://www.saffm.hq.af.mil/budget) the Air Force has concluded a hard target defeat analysis of alternatives and decided to start developing an advanced bunker buster in the 5000 lbs class. It would include a modified jdam tailkit, which probably means it won't be rocket boosted, but a very low risk option. The project will starf fy2018 and should finish development in fy2021.

Thanks for all the answers, didnt expect such quick responce.  ;D

Jets would be too slow to accelerate, however many jets towards the end of the war were proposed with reusable liquid rockets for assistance in taking off - so a hybrid rocket-jet with a large enough wing to allow landing at low speeds is a plausibility.

What about more powerfull catapults? A jet with low stall speeds could get airborne. AFAIK, Henschels Hs 132 was supposed to be an anti-shipping design at first, so it could be navalized if Kriegsmarine wanted so (correct me if I am wrong). It also had a pilot in the nose and in prone position = better visibility.

The most likely candidate to me would have been the Fw 190.

I get your point for this airplane up untill the point where later variants of F4U Corsairs would be leased to British carriers. From that point on, Wulfs would have a hard time.


Also I've seen mention of a  Blohm und Voss asymmetric design (P.62) as a "Marine-Stuka" but I have no idea if that was meant to be carrier-based or not.


Do you have any pictures of it, because I cant seem to find it on the internet.  :-\

Designation Systems / Re: Junkers J-Series Designations

Just finished mine. It's a great book with some beautiful photos. There are some unknown terms to me and the odd minor mistake -
 Julian Lake commanded VF-74 not Julian Gray . There's lots of information on the ejection seat problems (scandal?) and the whole rebuild/rework saga tells us that the F-35 programme's travails are nothing new.
