Either would last about 2 seconds with a F-18 or -16!

Ghaher-313: a detailed analysis, how and why?

Iranian armed forces again shocked the world by revealing a new domestic warfare. Ghaher-313, codenamed F-313, was set to show on a rotating stage inside a commercial hanger in Islamic republic Iran Air Force (IRAF) Tactical Air Base No.1 (TAB.1) located in Mehrabad airport in Tehran. The unusual appearance of the aircraft set a blaze on aviation and military think tanks and forums to debate and understand the agenda behind revealing such weapon. But to do so, one need to know about background of Iranian aircraft industries.
Background:
Iranian ambition to develop domestically made fighter jets was initially developed in mid 80s when during a formal visit to one of IRIAF air bases, Ayatollah seyyed Ali Khamenei, Iran’s then president and incumbent supreme leader of the country ordered the base staff to start repairing more than 50 percent damaged F-5 fighter jets. Direct command of the supreme leader of the country indicates eagerness of Iranians to make indigenous fighter aircrafts, the reason behind which may be found at critical situation of IRIAF both in start and during the 8 year-long frustrating war with Iraq. During the war and losing support of united states significantly affected capabilities of IRIAF and although it had done some of most notorious air raid (like H3 ride) and some of most brave air interception missiles (like khark incident and 1 to 13 dogfight of an Iranian f-14) but especially in last year IRIAF was weakened and wasn’t the significant factor same as starting years of the war.

Iranian experience in building aircrafts started in 1985 by repairing a more than 50 percent damaged F-5E Tiger2. Reportedly first completely homemade F-5E was set to begin test flights in 1993 and the second aircraft started its test flights in 1996. The aircrafts named Azarakhsh and entered service inside F-5 squadrons early 2000s most probably located in Dezful air base.
In a parallel process, different parts of IRIAF started copying different aircrafts such as FT-33s and PC-6 trainer aircrafts under the names Parastoo and S.68 accordingly. The most interesting effort of Iranian aircraft industries is Tazarv trainer jet, which itself is a result of evolution of two initial models, Dorna and Tondar. Tazarv demonstrated capabilities of Iranians in producing subsystems and independently designing a new airframe. The jet reportedly used a J-85 engine, belonging to F-5s purchased from US as spare parts for Shah’s F-5 fleet. There was a crash report on one of latest models of Tazarv in preparation for a major parade. There is not any indication or observation reports form any of Tazarv or even Dorna or Tondar models since the crash.
In early 2000 aircraft industries in Iran saw a major restructuring scene. HESA a company which originally established to assemble us Bell-214ST Isfahan and F-16s was instructed with gathering aircraft design and construction projects and establish construction lines in “Shahin Shahr” facility. However for unknown reason IRIAF continued to work on its projects and introduced Saeghe fighter jet several years later. Saeghe was a twin tail version of early F-5s. Meanwhile HESA participated in Russian M-ATF project introducing Shafaq light attacker jet. However none of introduced projects are believed to be reached to production line and entered service.
Gaher-313
After years of evolution, at last Iranian SAHA industries (instructed with aircraft maintenance and apart from HEAS industries) revealed the Ghher-313 project. Judging from appearances, such as fiberglass plates in cockpit and plaxy glass canopy, the demonstrated model is a scaled mockup of the original plan. The footage of 1:10 scale model flying above an undesignated runway also indicates that no actual prototype is built yet. However, investigating the odd conceptual design of the demonstrated model reveals a lot about agenda behind Iranian fighter program, if there is any program.

The revealed model uses a tandem wing configuration, a set that hasn’t been observed in any advanced in-service fighter jet. However the tandem wing configuration enables F-313 to have a large wing area in a relatively small space such as any twin wing configuration interaction of wing tip vortices would be a major problem, lowering the performance and increasing vibration of the wings even resulting an failure in wing structure and braking rear wings. To overcome such peril, designers bended the rear wing’s tip, distancing rear wing tip vortices from front wing perturbations. Blended wings also are prone for increasing aircraft stability in roll axis especially in high altitudes the same as tandem wing- horizontal tail configuration for yaw axis. And stability is a quality that fighter interceptor jets such as F-15 or Su-27 don’t favor in the contrary; bombers such as F-111 or Su-24 seek more stability to do more accurate bombing rides.
Nose of F-113 is also interesting, there is a relatively small nose (comparing with canopy size), lighter interceptor aircrafts especially modern 5th generation fighters need large sophisticated radars with lots of capabilities such as low probability of interception and jamming resistance capabilities, there for fighter jets usually have big noses to host big radars. But on the other hand bombers doesn’t need large and sophisticated radars but they relay mostly on optical targeting pods and data network for target acquisition.

Another important sign is small size air intakes which are located above the body. Is such configuration in severe maneuvers, separation of air flow from body would block entering air to engines and make the turbofan engine stall. However capability of performing severe maneuvers is crucial for evading missiles both in fighter jets and bombers but for aircrafts flying in high altitudes due to decrease in air density its almost impossible to perform high g maneuvers. Therefore they rely on high speed jamming, stand off attacks and stealth as their win cards. Up-intakes are also observable on F-117, B-2 and RQ-170 bombers and recon aircrafts.
All signs indicate that F-313 is designed to perform attack or strike sorties in high altitudes using ECM and low RCS as its main threat evading tactics. The bomber would probably use stand-off weapons such as domestically made GBU-130 or GBU-15 Ghadr bombs and land attack versions of C-802 missile. Since US air force and its allies have tendency to defend their airspace by interceptors and have little attention in development of counter guided munitions systems such as pantsire.S1 F-313, at least on paper, would be a serious threat for western defense strategies.
However looking good on paper, the history of Iranian air craft industries remember a lot of good looking projects which faded away by the time passing lux revealing ceremonies. The story of Ghaher-313 shows a little difference with those in the past.

From Wiki...

Doubts of viability of aircraft

There has been no independent verification of the status of development of this aircraft, and some commentators have even claimed that the aircraft is a hoax, or a "laughable fake".[17] Media sources outside of Iran have raised the possibility that the demonstrated aircraft would not be able to meet stated performance and/or that it may be a scale prototype or mockup,[18][15][19][20] with Cyrus Amini, a BBC News Persian Service journalist[21] claiming that the aircraft "looks like a cheap copy of the American F22".[4] Iran does not release technical details on its arsenals, so many of its claims about the aircraft are impossible to verify.[22]
According to Flight Global, unnamed Israeli experts say the "indigenous fighter jet" Iran presented on 2 February is nothing more than a "very sleek plastic model". Further, the canopy appears to be constructed of "basic plastic," the air intakes are unusually small, and "The whole impression is of some plastic parts pasted to an old flying platform." One expert says the cockpit and ejection seat seem real, but the Qaher-313 displayed seemed too small to be a capable fighter. A photo of the cockpit shows a simple glass cockpit design using civilian avionics from Dynon Avionics and Garmin which are normally found on much less sophisticated general aviation aircraft. The markings on the backup airspeed indicator in this photo seem unrealistic, suggesting a stall speed in landing configuration of merely 70 knots and a never exceed speed of about 260 knots; values more likely to be found on a small turboprop aircraft.[23] Video footage showing the plane airborne could have been a radio-controlled model aircraft. Poor-quality footage posted on the internet provided no sense of scale for the platform being flown, and also failed to show its take-off or landing. Its stealth factors are also claimed to be into question, having no visible weapons carrying capability, either internally or externally.[24][25] Iran has stated that the videos are of small radio controlled jet and propeller models and not the full size airplane. Furthermore the animation provided by the designers shows two internal weapons bay under the wings.[9]
The Times of Israel labelled the aircraft "a hoax". Israeli aeronautics expert Tal Inbar claimed, "It’s not a plane, because that’s not how a real plane looks. Iran doesn’t have the ability to build planes. Plain and simple." Iran claims that it has produced and deployed a squadron of Northrop F-5-based HESA Saeqeh fighters[26] as well as several other training and civil planes. Military aviation journalist David Cenciotti[27] stated that the aircraft has "implausible aerodynamics and Hollywood sheen", claimed that it is too small to be a real fighter jet and that the cockpit was too simple and was "similar to those equipping small private planes".[25]
One Israeli aerospace engineer speaking anonymously to The Times of Israel indicated that while the aircraft displayed was obviously not a flying example, it did show advanced stealth features and that the design could be capable of high maneuverability. He stated that while the aircraft lacked bomb-carrying provisions it could be an effective interceptor. He concluded, Iran needs "a defensive interceptor that gives them the element of surprise, and it is big enough to carry real air-to-air missiles."[25]"

Why is this non-existent aircraft being discussed in the Card Models>Model Builds>Aviation section? Is it because it is not a real aircraft but rather a paper model? I understand the Canadians are working on stealthy, ceramic armored Sno-Cats in preparation for the invasion of the USA next winter...now there is a serious subject for discussion (in AirDave's Canadian forum, of course.)

Careful...that could be construed as political comment!
At the very least it might be an attack on Canadian Cats with Snow Blowers!

yeah...how did this topic end up getting posted in the Card Model Builds section? rofl
And it was started back in '07 ?

Snow blowers paper models, Dave?

At least we can invade IPMS with paper models... politics aside.

I bet someone, somewhere, is designing the paper model of the F-113 anyway.
