The Super Tomcat 21 would be a modification of the original F-14 design and it was to feature GE-F110-129 motors that would allow the Tomcat to super-cruise (achieve mach 1+ without using afterburner) continuously at mach 1.3. Additionally, the jet would have an upgraded APG-71 radar, modified and enlarged control surfaces, and enlarged leading edge root extensions (LERX) that would house more fuel and enhance the jet's low speed handling capabilities. Thrust vectoring nozzles tied directly to a new digital flight control system were also an option. These modifications would give the "Turkey Bird" true super-maneuverability and eye-watering acceleration and sustained speed. Additionally, super-cruise combined with its additional internal fuel carriage capacity would have given the Super Tomcat much greater range than it already had. The jet would also be able to carry targeting and navigation pods, giving it true multi-role capability. Finally, a new single-piece windscreen would be added to provide much better forward visibility.

It would have had a sustained 77 degree angle of attack without relying on vectoring nozzles, as well as carry any ordnance F-15 can.

It's a great airplane but this thing killed the portion of the ATF program designated for the Navy (NATF), and I can't forgive that.

Naval Advanced Tactical Fighter (NATF) 1988-1991 - Due to Congressional intervention, the US Navy agreed to evaluate a navalized version of the US Air Force's Advanced Tactical Fighter (now the F/A-22) as a possible replacement for their F-14s. In return, the US Air Force would evaluate a derivative of the ATA as a replacement for their F-111s.

In late 1988, a Naval ATF (NATF) program office was set up at Wright-Patterson Air Force Base and the existing ATF Dem/Val contracts were modified to include studies of potential NATF variants.

The Major Aircraft Review reduced the peak production rates of both the ATF and NATF. This had the effect of substantially increasing the program cost. In August 1990, Admiral Richard Dunleavy, who was in charge of Navy aircraft requirements, stated that he did not see how the NATF could fit into any affordable plan for naval aviation. In early 1991, before the final contractor for the ATF was even selected, the consideration of the NATF was dropped. This was mainly due to the fact that the Navy realized that a series of upgrades to their existing F-14's could meet the Navy's air superiority needs through 2015.

The F-22N was studied in the Major Aircraft Review as an NATF concept, and canceled in large measure because the projected high gross take-off weight exceed the capacity of current carriers. http://www.globalsecurity.org/military/systems/aircraft/natf.htm

Carrier aircraft fly slower approaches than land-based aircraft and must be able to perform a waveoff at low speed. Therefore, a full power 1.5g turn at 0.2M and sea level with all stores and reserve fuel on board may be needed to ensure an adequate maneuver margin. This requirement determines the wing loading for sea-based aircraft [the SSF was exempt from this waveoff requirement because it performs vertical landings].

Carrier operations require heavier structures for several reasons: 1) arrested landings require a tail hook and reinforced fuselage, 2) landing gear are designed for 24 ft/s sink rate, and 3) catapult launches require reinforced nose gear and a strengthened fuselage. These weight increments are difficult to quantify because there are no data for aircraft that were designed for both land-based and sea-based operations with exactly the same mission capability. For example, contrary to the expected navalization penalty, the land-based F-4 actually had a higher empty weight than the carrier-based version. But in this case the land-based version used the increased strength and wing area of the carrier aircraft to carry an increased equipment load, which equates to higher mission capability. Similarly, few aircraft have successfully made the transition from land-based to sea-based operations. The carrier version of the British Hawk did perform catapult launches and arrested landings but required substantial structural reinforcement to do so. The navalized Hawk is approximately 11% heavier empty, but it can no longer fly as far as the land-based version.

Since historical research did not provide values for fuselage and landing gear weight penalties for carrier operations, an estimate had to be made another way. To this end, the F-14 and F-18 were modelled using ACSYNT's land-based weight equations. The actual aircraft fuselage and landing gear structure weights were approximately 30% greater than those modelled by ACSYNT. Therefore, 30% fuselage and landing gear weight penalties may be applied to carrier-based aircraft in this study. Informal comments by US Navy personnel agreed that 30% was a reasonable estimate.

Early in the ATF/NATF development, a Naval variant of the F-22 could have been developed. By the late 1990s, however, to graft a Naval requirement onto an existing F-22 program would be similar to the mistake that the Department made in developing the F-111. In that program, DOD directed the Air Force to add Naval requirements to an existing Air Force EMD concept "with minimal disruption" to the program. As a result, the Naval version of the F-111 was significantly overweight and subsequently canceled in favor of a new start Navy aircraft, the F-14. The appropriate time to join multi-service requirements is early in the program, and the ideal time is while the requirements are being developed in a balanced systems engineering approach.

  Praised as the greatest tank of all times in the US and northern parts of Saudi-Arabia, in reality the M1A2 SEP is nothing to write home about. A detailed comparison to an older French design revealed, once again, that more expensive does NOT = more effective. In fact, the M1A2 SEP is nowhere close to being the best MBT around.

Tyre is an ancient city.

Tire is short for attire, meaning the metal dressing on the rim of spoked wheels, c1300. It was misspelled as tyre a few hundred years later and that became popular. Then the grammarians fixed it back to original in 1600, which is when America started saying it. And now retarded British schools are bringing the misspelling back again just to be different from America.

This is probably one of few cases where Americans are using proper English spelling.

I hope you got a deal on those, I bought my mom a set of Michellens for $410 installed after mail in rebate in that time frame. For future reference if you drive on a popular size, you can sometimes get slightly used tires for hella cheap. I got a set of good tires on steel wheels for for $300 for my expedition. F150s are as commons as Asian people in China out here, but still a great deal. Retail on that would have been about 1k.

All told the tires were $500 and then I paid some russian guys $100 to balance them. I didn't find them cheaper anywhere else that wasn't sketchy OR would only sell them to me if I had them put on there at an exorbitant service charge.

The rear extension levers (right hand) aren't adjusted right (i've got the hoods way too far forward so I can get fingertips on the brakes when in the drop). It's bent to hell and back.
The front brake is the brake that matters.

It's got some quirks, I need to adjust the shimano 600 derailers because it's a friction shift setup but it's also just need to put some miles on the bike as well.

The New $3B USS Zumwalt Is a Stealthy Oddity That May Already Be a Relic
12.10.15 http://www.wired.com/2015/12/the-new-3b-uss-zumwalt-is-a-stealthy-oddity-that-may-already-be-a-relic/
AT FIRST GLANCE, the long-awaited USS Zumwalt looks more like brutalist Soviet architecture than a destroyer in the United States Navy. But despite appearances, this trapezoidal hunk of gray steel was built at Bath Iron Works in Maine, not plucked from a Bulgarian mountaintop.

The Zumwalt completed its first at-sea tests this week, and its captain, who really is named James Kirk, couldn’t be happier. “For the crew and all those involved in designing, building, and readying this fantastic ship, this is a huge milestone,” he says. Bath Iron Works employee Kelley Campana, with tears in her eyes, told the The Telegraph, “It looks like the future.”

Maybe so. But the Zumwalt, named for Navy Admiral Elmo Zumwalt, may already be a relic.

The Zumwalt-class destroyer program started in the early 1990s and has been a problem child ever since. At first, the Navy planned to purchase 32 of the stealth vessels. Then it said it would buy seven. Then three. Now, it may buy just two. After decades and billions of dollars spent, the DoD may instead choose an updated version of the Arleigh-Burke DDG-51 destroyer, a model that entered service in 1991.

- ATLANTIC OCEAN (Dec. 7, 2015) The future USS Zumwalt (DDG 1000) is underway for the first time conducting at-sea tests and trials in the Atlantic Ocean Dec. 7, 2015. The multimission ship will provide independent forward presence and deterrence, support special operations forces, and operate as an integral part of joint and combined expeditionary forces.

Yeah, the point is to fool those hideously destructive anti-ship missiles if you cannot swat them down (or destroy their bombers, ships, subs or launchers) at distance.

The ship’s tumblehome hull is plainly visible in this sharp bow view. Unlike more conventional hull forms, the tumblehome hull is fuller and wider at the waterline and below than above. The ship’s maximum beam is 80.7 feet on a length of 600 feet. http://jamesgzumwalt.com/the-latest-pictures-of-the-uss-zumwalt/

They needed that armor when the Japanese shell started ripping in.
But that historic battle in the Leyte Gulf of the Philippine Islands stands testament to how a small screening force of destroyers were able to unnerve and frighten away a much stronger attacking enemy fleet of cruisers and battleships who were about to destroy a relatively unguarded collection of escort carriers. The Japanese commander thought that US destroyers attacking his force so aggressively must have been the vanguard of a powerful American surface fleet and he fled ingloriously when he could have swatted away the escorts and destroyed the carriers.

So, it's official. The UK is to purchase 9 P8 Poseidon aircraft to replace the scrapped Nimrod. if you ask me, this is what they should have done in the first place. Remember the Nimrod AEW clusterfuck, when we spent large sums of money on a plane that didn't work, then had to buy an off the shelf US design (Sentry)? Well, history has repeated itself, with the Nimrod MRA4 being scrapped and now we are looking to Boeing (again) to fill the gap.

I dimly remember reading something like they left space in the design so they could retrofit a catapult if required.

Don't forget this thing has a 50 year service life expectation. there's nothing to say it wont get one in 2035 or so in an upgrade pack, when the MOD gets round to buying Navalised Super Typhoons.

>> No. 19553 ID: 794d7b
Honestly I don't really know whether or not that was the case; I guess you'd have to ask the British government for the specifics of the estimated costs. The ships were actually originally planned to be STOVL and a decision was made in 2010 to build them with cats instead, but the projected cost to do so apparently doubled from its original estimate sometime afterwards and they reverted to the original plan in 2012. I remember there was a big kerfuffle about it in the UK a few years back and a lot of Royal Navy guys were angry, so I guess somebody in the government must have screwed up when estimating the costs.

The BMD-4 airborne combat vehicle is fitted with a 100mm 2A70 low-pressure rifled gun, a 30mm 2A72 coaxial autocannon, and a 7.62mm PKT coaxial machine gun.

As one of the most heavily armed IFVs, the BMD-4 possesses multiple secondary armaments. These secondary weapons include a 30 mm AGS-30 grenade launcher, a 5.45 mm RPK machine gun, and a 9P135M launcher post capable of firing additional anti tank missiles. The AGS-30 and RPK are both operated by passengers seated towards the front and bow mounted towards the left and right respectively. Both of these bow mounted weapons are dismountable and man portable for increased versatility. The 9P135M missile launcher is mounted towards the roof and is also dismountable. https://en.wikipedia.org/wiki/BMD-4

Oh wow, that's the FMC downselect prototype. That's not even up to full M8 type status yet. That'd be neat to see. That'd be from 1991, 1992 at the latest.

The M8 has a different gun, the shorter M35 105mm rifled gun, whereas this still uses the M68. This thing also is fitted with fixed armor, whereas the base M8 is lighter by 2.25 tons because of the move to stages of armor fittings. This thing's got a different engine too, because the M8 was standardized to run on JP-8 or diesel.

Some lucky son of a gun got something important on that winning bid. The M5 Stuart would have been fun to bid on too. Oh man, lot 1084, an Ontos! I've loved that thing ever since I first saw it at the Rock Island Arsenal Equipment Display as a kid. Doesn't come with the guns though. Shame, that be a fun armored gokart for $20,000.

And the L7 is arguably not useful for fighting anything newer than a T-62. Even export model T-72s with downrated armor were scaring the hell out of analysts, during Lebanon and the Iran-Iraq war it repeatedly came out on top against the M60, Chieftain and Merkava.

Off the top of my head the only "light tanks" in service that mount full-size guns are upgrades to the Italian B1 Centauro, and the Sprut. The Rooikat, XM8, Vextra 105 and CV90 have all been prototyped with various low-recoil 120mm guns but none are in service. The Chinese had the Type 89 tank destroyer but it's just been retired and I question if Chinese 120mm ammo is any better than modern 105mm ammo.
