As I said on the KF-X thread, I highly doubt the hypothetical KF-21 Block III will be an effective stealth combat aircraft with the current internal fuel capacity of 12000lb. It will carry about the same of even less payload than HAL AMCA which employs the same engines. KF-21 requires a complete...

Korean understands your pain, my friend. KUS-FS (Korean MUAV) made a maiden flight in 2011 and was only approved by the Korean army in May, 2022 after 11 years of delay. Weapon integration has not even finalised (It is still strictly a surveillance aerial vehicle).

I think we should evaluate the internal fuel capacity of KF-21 by comparing KF-21 with other 5th gen aircrafts that are already in service & development. Almost all of them have a large airframe to internally accomodate both a sufficient amount of fuel and weapons since engineers understand that...

Anyway, KAI and PTDI have agreed to develop a special 480 gallon drop tank for IF-X rather than a standard 370 gallon drop tank for KF-21 and that alone should add additional 850 kg of fuel in combined and be able to increase the ferry range meanigfully.

Not sure how obvious it was since you replied to this specific quote Clearly I was talking about hypothetical KF-21 Block III, the 5th gen fighter aircraft and I plainly explained my reservation as KF-21's seemingly lack of internal fuel in contrast to F-35 will limit KF-21 Block III's role as...

You are just wrong. IF-X has already distictive features to satisfy Indonesia's tailored needs as they were specified by Indonesia from the very beginning. For instance, KF-21 is designed to do aerial refueling via the flying-boom system, but IF-X is designed to do aerial refueling via the...

However, I might concur that KF-21 isn't suitable for Indonesia as the aircraft can only fly with 2 drop tanks and has a shorter ferry range than Rafale (2900km vs 3700km). However, I thought that was the whole purpose of Indonesia getting a separate prototype for IF-X as Indonesia would be...

The Philippines seems to be interested in the aircraft. It is alledged that a few other Asia Pacific & European countries have also expressed interest in the fighter jet. However, the main user is still ROKAF and Korea is already prepared of Indonesia dropping out from the project. Korea prefers...

ROK has anounced plans to develop various missiles for KF-21, including both short-range and BVR AAM. However, the airforce will continue using American missiles including AIM-120, AIM-260 and European missiles such as the Meteor because a) Korea is planning on being an ally of the United States...

I am not sure how could you claim the Internal fuel capacity is not one of the biggest problems. It means KF-21 Block III could play a severely limited role in intercepting hostile aircrafts. Additionally, KF-21 Block III is designed to carry only 2 X AIM-120 missiles & 4 X 250 pound GBU-39...

KF-21 won't be a 5th gen fighter jet anyway as the aircraft could hold only 12,000lb (about 5,500kg) of fuel internally. This will severely restrict its combat radius. By contrast, F-35 is designed to carry 18,250lb (about 8,278kg) even though it is a single-engine fighter jet. This is why there...

Probably It will be a better project than the French-German-Spanish FCAS as French seem to always be in conflict with other participants and German seem to always complain about their seemingly lack of industrial input of the project. They didn't learn anything from Typhoon.

I thought Malaysia requires the manufacturer to start delivery of their new LIFT & LCA aircrafts within 36 months of the contract signing which is expected to be taken in place this year? Then again Tejas LIFT isn't actually a thing from what I have heard and FA-50/M-346FA currently don't have...

At Gebze Technical University (GTU) Aviation and Space Summit 2 event, Mr. Kotil claimed that the work for an armed variant of Hurjet which is dubbed as Hurjet-C could continue until 2027 even after TAI is expected to deliever the first aircraft to Turkish Airforce in 2025. Wouldn't this mean...

Thanks, mate. I appreciate it. However, I honestly don't think highly of KF-21. KF-21 will 1) have about the same payload with F-16 (about 7,700kg / 17,000 lb) 2) probably have a high maintenance cost as the aircraft has two engines (vs. F-16) 3) have shorter Ferry Range than F-16V (2,900km...

What I find interesting that is the video clip that Mr. Kotil alledgedly said that Hurjet will carry 5 tons (5,000kg) of bomb is not even the latest. Mr Kotil said this on 17 Apr 2021. This is around the time when the CDR of Hurjet was alledgedly completed in 2021 and TAI's website &...

The argument that I keep hearing is that the website & (the official broucher) could be outdated, but the undisputable fact is that TAI did update the estimated specs on both website and the broucher since TAI selected GE F404 engine and those figures are almost identical to what TAI advertised...

Before I go, I like to than you all forum participants who reponsded & provided a link. However, I wish that somebody had an answer for Ferry Range & Wing Area. I am kinda found the answer for Wing Area by myself, though. I find it bizzare that nobody has noticed the simple conversion error.

Alright, you don't care about the specs on the company's website & broucher. That's fine. I am not here to pick up a fight. What you said simply doens't matter when it comes to aerospace engineering. You can build many mock-up as possible, but you can't drastically change the specs once your...

I have already proved that TAI's website did update accordingly when they decided on the engine. This is almost the identical specs when they completed the CDR. I think you'd better question his words if that's what he actually meant because once the CDR (Critical Design Review) is finished and...
