A proper WDNS (weapon delivery and navigation system), new MFDs, compatibility with smart munitions of the 90s, and other new sensors.

It is the Skyhawks starting up they use the Hornet Engines

@@Aviation_Videos The scooters used the Pratt & Whitney J52 engine & the Hornet used General Electric F404-GE-402 afterburning turbofan engines. I've heard Hornets starting on many occasion from my house near RAAF Darwin. I've only ever heard Hornets make that whining sound on start up

Google A4SU Skyhawks that what these are and they use F404s

@@Aviation_Videos Did not know that. Thanks for the info must of been non after burner. What a weapon the A4SU would of been. I use to watch the Scooters as a kid at HMAS Albatross & they never made that sound starting up & that would be why.👍

@@matk4731 yeah I thought the same sounded like hornets starting up did a little google and saw they used F404 it would be an awesome little jet to fly around

Hi Paul, RSAF’s two-cockpit skyhawk variant was around since early 70s. The A-4s incorported the new GE engine in the late 80s after a series of crashes showed up the age of the PW engine

@@IRP01 What a hot rod with the F404!

Correction - that's F5E Tiger II.

no point; 1) the re-engining was mainly to solve reliability issues from the ageing J65s; in fact the particular f404s installed were down-rated to about 11.5k lbf dry 2) skyhawk's airframe was not rated to go past m1.0: it could but it would return damaged 3) the thing already had greater t:w than contemporary f-5's going at full afterburner! During tests, the su would outrun the f-5 chase planes especially at low altitude

@@aaronquak2139 Thanks! I knew they had to replace those J65s. I was initially curious also as to why they didn't choose the tried and true J52-P408, which had slightly greater thrust than the GE F404, but let me guess: age, weight, and fuel efficiency.

@@19580822 yes; by 1985-1992 you couldn't buy fresh J52s anymore. PW were willing to restart the production line, but the F404 was selected over the J52 and RB199 then under consideration. In any case the 404 was more reliable and serviceable, being designed for the Hornet, and was much lighter than the J52. ST Aerospace probably saw it as a chance to develop in-house capabilities too. The earlier TA-4S/S-1 were also totally different from US TA-4s and retained the J65 for commonality.

I used to work at McDonnell Douglas and one of the old salts told me that they once put an afterburning F404 in a Skyhawk as an experiment. He said the thing was a beast. I have no verification of that, though.

​@@edwardbarocela3064Sounds about right - it would have been a beast!

Semper fi sir! Much respect!

Singaporean not NZ

Only effective as a light bomber in the aftermath of an invasion.

Do u know that the A4SU is smaller but it can carry heavy ammunition and acts as a fighter bomber. Other aircrafts will need to fold its wings when they are stored in an aircraft carrier but A4 need not. With its short take off and short landing abilities, it can still match any modern aircrafts today. Served as an carrier airborne fighter bomber, it will remain and still is a threat to any modern naval fleet today. The day of A4SU fighting in a war may not be over yet especially with its ability to carry nuclear weapons.

@@kambehlan9216 subsonic speed is its drawback bro.

Phased out more than 10 years ago .

En el 82 los argies con Skyhawks de los 60 mandaron varios buques piratas del tipo 21-22 y 42 al fondo del mar

If my memory serves me right RSAF skyhawks flew well into the early 2000s.. 145 Sqn might be the last to fly it

142&143.@@25foxbat1

Yeah, it says “archives” in the title... And “1990” in the description...

El modelo que usan los Singapurenses es muy distinto al que tiene casi todos los operadores (incluidos nosotros los Argentinos) ya que comunmente el modelo de entrenamiento; es de una cupula singular; mientras que el modelo SU es la fusion de 2 cabinas del A-4 normal en un mismo fuselaje (con un diseño que recuerda al helicoptero ruso el MI-24), quisas lo hicieron con el proposito de darle un "realismo" mejor al entrenamiento del pilotaje de estos scooters.

this was the 90s bro

Yeah, even the uniforms were old... The technicians wear pixelated camos nowadays like the USAF. The uniforms you see here is like 2-3 generations ago.
