Gloster F.35/35 revamped from Mercury to Bristol Taurus

So, before it's demanded, I put this thread in this section.

Thanks for the move. o7


Also, as someone previously mentioned, landings would also be very tricky. Even postwar, there were many landings where airplanes barely hooked on the last wire. So the dream aircraft would need to have the following:

-Low stall speed (~150 km/h), high speed in flight (~450 km/h in level flight, this doesnt apply for recon airplanes) (Ju 87 and Fieseler Fi 167 fail)
-High responsiveness of the engine (all-jet airplanes fail)
-Great visibility (this is where both Fw 190 and Bf 109 fail imo)
-Agility (some versions of Fw 190 were extremely heavy due to armor, reducing agility)
-Strenghtened landing gear and foldable wings (achievable on almost any type)
-Good payload (doesnt apply for recon airplanes as well)

Possible designs that fulfill all or majority of the above mentioned criteria:

-Blohm & Voss P. 194 (asymetry could be effective). If this would be used, BV 141 could be used instead of Fieseler Storch due to same exact piston powerplant as P.194.
-Fieselers Storch (can land almost vertically, doesnt take up alot of space).
-Messerschmitt / Blohm & Voss Me/Bv 155 (as it was designed for carrier service in its early form).
-VTOL designs, like Heinkel Lerche (very Luft 46-ish).

Ask Japan for help.

Missile Projects / Re: Patriot SAM replacement

The Army had awarded Lockheed and others R&D contract under APASS..Not sure if actual test hardware came out (they are still working through it till next year) of it but something that could well be considered for future Patriot (PAC-3) upgrades.

Affordable Active Phased Array Sensor Systems

Quote
It is the Government's intent to award a cost plus fixed fee, five year, indefinite delivery indefinite quantity with task orders type contract for the Affordable Phased Array Sensor System (APASS) Program under the U.S. Army Aviation and Missile Research, Development and Engineering Center (USA AMRDEC). The AMRDEC seeks innovative technologies to advance capabilities in applied sensors guidance electronics for Radio Frequency (RF) and Millimeter Wave (MMW) technologies. The objective of this development program is to design, fabricate, and demonstrate an affordable, solid-state, form-factored all-weather Active Electronically Steered Array (AESA)-based seeker with the capability to engage ground targets, cruise missile, UAV, and rotary aircraft threats, and to serve as a building block for radar system development that could serve surveillance or fire control functions.The proposed period of performance is from 28 February 2013 through 27 February 2018. Based upon market research, the Government is not utilizing the policies contained in the Federal Acquisition Regulation (FAR) Part 12. Authority cited: Statutory authority permitting other than full and open competition for the requirement is 10 U.S.C. 2304(c)(1), as implemented by paragraphs 6.302-1 of the FAR, entitled, "Only One Responsible Source and No Other Supplies or Services Will Satisfy Agency Requirements." This acquisition will be sole source to Lockheed Martin Corporation, 5600 W Sand Lake Rd MP-265, Orlando, FL 32819. Lockheed Martin possesses a unique capability for the specific sensor component design and test requirements involved with this acquisition. Consequently, they are the only source known to the Government at this time that is currently capable of resolving technological problems with sensor system prototypes that may arise during development and testing given their previous successful performance in design, demonstration and development of thermal management techniques. Lockheed Martin is the sole designer and manufacturer of the current prototypes; no other company is known at this time that is capable of performing the unique design, development, integration and test requirements required under this acquisition for phased array sensors of tactical grade quality. Lockheed Martin utilized their own proprietary data/processes to design and develop this emerging technology; therefore, Lockheed Martin is the only source currently capable of providing the specialized design, development, integration and test for continuing development and modifications to this unique and proprietary concept.

IN BRIEF: Lockheed Martin to provide Army with radar sensors for missile guidance


Quote
U.S. Army missile experts needed advanced radar missile seekers for air- and ground-based systems across several frequencies. They found their solution from the Lockheed Martin Corp. Missiles and Fire Control segment in Orlando, Fla. The Army Contracting Command at Redstone Arsenal, Ala., awarded Lockheed Martin an $8.2 million contract for Affordable Phased Array Sensor Systems (APASS) technology for a variety of applications. The APASS Ka-Band Medium Power Development program, sponsored by the Army Aviation and Missile Research, Development and Engineering Center (AMRDEC) at Redstone Arsenal, is developing phased-array radar technology for sensors guidance using RF and millimeter wave technologies. The program is developing affordable, solid-state, all-weather active electronically steered array (AESA) radar seekers to enable missiles to attack enemy ground targets, cruise missiles, unman-ned aerial vehicles (UAVs), and helicopters, and to serve as a building block for future radar technologies for surveillance or fire control.

Issue #02 "Rocket fighter Special" includes:


    Bell Rocket Fighter: A design similar to the X-1
    North American RD-1381-B: A two-stage VTO design
    Boeing Model 457: A rocket boosted ramjet fighter with two stages
    Truax Rocket Fighter: A VTO ship-launched interceptor
    Northrop XP-79: A flying wing with a prone pilot
    Lockheed CL-362-1: A late 1950ís spaceplane-like hypersonic concept
    SAINT II: the Satellite Interceptor lifting body
    Bell D-35: a tailless delta-like design

The argument about the cradle system is valid, I think, as is the the one about the narrow track of the Bf 109 landing
gear. The Seafire was described as a "great carrier fighter in the air, but it really should have stayed there ...". and
it had principally the same type of landing gear.
The choice of the Bf 109 as the fighter for the GZ was simply based on the availability of this type, as the only
suitable German fighter in that time, the Fw 190 was somewhat later, when it became clear, that one type wasn't enough.
The same is true for the Ju 87, though it may have been better suited to the use on a carrier, than the Bf 109.
The existence of a German carrier task force could indeed have had tremendous impact on the naval situation between
the Kriegsmarine and the RN, but ... probably even two carriers wouldn't have been enough and to think just about one
really means drifting into alternative history. So, before it's demanded, I put this thread in this section.

Hearty congratulations!

Just came back from a strenuous bike ride to this and after having a shower will be cooking - bit of a coincidence, admittedly - Boeuf Stroganoff :)

There's going to be some wine left over too, I'll be raising a glass in honour of Irkut and their team!
