Do singapore need fighter planes like Harrier?
-
Discovery ch did show a German pilot demonstrate it before, forgot the plane name, think is X36. It show a F15 limit to twist while this X plane can be very agile.

is X-31.....check my previous post.....*pengs*Originally posted by T.Ryousuke:Discovery ch did show a German pilot demonstrate it before, forgot the plane name, think is X36. It show a F15 limit to twist while this X plane can be very agile. -
Wat e pt of such an agile aircraft if your pliot cant handle e G-force, for example e SU-37 max G-limit +10/-4 due 2 its thrust-vectoring but i think e pliot will most likely suffer from G-LOC
-
New G-suits now allow pilots to withstand up to 11-gs. =)
-
U mean like those G-suit specially designed for Gripen n Typhoons?

nw most G-suits can handle more Gs compared to last time......Originally posted by spartan6:U mean like those G-suit specially designedfor Gripen n Typhoons? -
I C guess im outdated liao

This technology is expensive for its maintenance and facilities, they claim that this JSF will rule the sky for next 50 yrs. It's a race btw the two super power or maybe Europe. That's why RSAF can buy the F15 from US as they try clear their stock, and maybe they can buy the 2nd hand Harrier from US. SAF always look for cheap and good stuff with proven track record. I heard a JSF cost around US$45mil or maybe is the Rnd cost?

F-15 is almost going to shut down their production line for goodness sake....if not for S.Korea and Us buying it will stop anytime from now...as for F-35 the actual protoype testing have not in flight so i cannot comment much.....the X-35B weight and engine issue already delay the whole programme pretty a lot......Originally posted by T.Ryousuke:This technology is expensive for its maintenance and facilities, they claim that this JSF will rule the sky for next 50 yrs.

Cheap and good stuff? F-15SG is NOT CHEAP.......so is the PARTICIPATION of the X-35 PROGRAMME......
as for RSAF thinking of getting harreir type of a/c...i read in Flight international article before that they ARE INTERESTED in F-35B. Buying? dont ask me... -
Do you think singapore can get harrier first then considering getting F35 in future?Originally posted by tankee1981:Bro,the F-35 is not even operational yet! By the time they are sold to us 2nd hand it could be as long as 20 years down the road maybe even more!

harrier production has already closedOriginally posted by grandeur:Do you think singapore can get harrier first then considering getting F35 in future? -
How much SAF pay for the F15s? Incl. weapons? with backup support? with spare parts? incl. training ?Originally posted by duotiga83:F-15 is almost going to shut down their production line for goodness sake....if not for S.Korea and Us buying it will stop anytime from now...as for F-35 the actual protoype testing have not in flight so i cannot comment much.....the X-35B weight and engine issue already delay the whole programme pretty a lot......

it is not a misconception- they are able to take off vertically. The reason why they alway us STOVL ramp is because if they do vertical take off, it will eat up a lot of the fuel and limit the range.Originally posted by duotiga83:ppl got the misconception that harrier can take off vertically...IN FACT is SHORT Take off and Vertical Landing.....only F-35 can do vertical take off att he moment ( pioneer by Russia YAK-141 Freestyle) -
close to SG$1 million for a total of 12 a/cOriginally posted by T.Ryousuke:How much SAF pay for the F15s? Incl. weapons? with backup support? with spare parts? incl. training ? -
Shotgun is totally right, VTOL aircraft is not that vital and there is some short coming of it .Originally posted by Shotgun:I personally do not think that having a VTOL aircraft is vital.
Honestly speaking, if one runway is busted. The base would be pretty much gone too. The runway would be th least of the concern since it can be somewhat easily repaired by just dumping concrete into it, and leveling it.
Its Base infrastructures that would be hard to replace.
2ndly, if one runways is temporarily out of commission, can always divert to alternate. If all our runways are destroyed, we are screwed anyway, cos that would me a lot of infrastructure damage to bases won't it? So what if you have VTOL aircraft but have no capability to support operations?
Nowaday, with machines , one can easily repair the runway so easily, thus runway is not a problem.
it is fun to think that we can simply put one VTOL plane here and VTOL plane there, but in real life it is not that simple, planes need maintenance reloading and fuel, with all those VTOL planes distrubited may be nice to have, but it will face the issue of ground crews, supply and servicing .
VTOL planes usually is very short range, they used up a lot of their fuel in taking off. Thus usually they are more suited for ground support attacks then the heavy stuff. -
IF you are speaking of STOL a/c like that Gripen ....that might be a huge difference in terms of capability.......Originally posted by storywolf:Shotgun is totally right, VTOL aircraft is not that vital and there is some short coming of it .

Ya, That is what I read on the newspaper last time, tot I see wrongly. That's to say it is still very cheap compare to the F22 or JSF.Originally posted by duotiga83:close to SG$1 million for a total of 12 a/c -
$1 million or $1 billion?Originally posted by duotiga83:close to SG$1 million for a total of 12 a/c -
oops my mistake...is SG$1 BillionOriginally posted by twists:$1 million or $1 billion?
F-15SG
The F-15SG (formerly the F-15T) is a variant of the F-15E, currently ordered by the Republic of Singapore Air Force (RSAF) after a seven-year evaluation period involving five other fighter aircraft under consideration. The F-15SG was chosen on 6 September 2005 over the only remaining aircraft still in contention, the Dassault Rafale.
The F-15SG is similar in configuration to the F-15K sold and being delivered to South Korea, but differs in the addition of the APG-63(V)3 active electronically scanned array radar developed by Raytheon. Pending news on Lockheed MartinÂ’s F-35's progress, the RSAF has placed an order of 12 aircraft with an option for 8 more to replace its A-4SUs. The purchase is part of the New Fighter Replacement Program, worth about US$1 billion and which will be the most expensive single fighter aircraft purchase by the RSAF.
On 22 August 2005, the US Defense Security Cooperation Agency (DSCA) notified US Congress about a potential Foreign military sales (FMS) of weapons, logistics and training in the event that the Boeing F-15 was selected by Singapore. Since the F-15 purchase has now been confirmed, it can be assumed that Singapore will follow up on this proposed weapons and logistics package, worth a further US$741 million dollars if all options are exercised.
Weapons in this package include:
* 200 AIM-120C Advanced Medium Range Air-to-Air Missiles (AMRAAM)
* 6 AMRAAM Captive Air Training (CAT) Missiles
* 50 MK-82 GBU-38 Joint Direct Attack Munitions (JDAM) w/BLU-111 warhead
* 44 AN/AVS-9(V) Night Vision Goggles
* 24 Link 16 Multifunctional Information Distribution System/Low Volume Terminals (Fighter Data Link Terminals)
* 30 AGM-154A-1 (JSOW) Joint Standoff Weapons with BLU-11 warheads
* 30 AGM-154C (JSOW) Joint Standoff Weapons
* 200 AIM-9X SIDEWINDER Missiles
* 24 AIM-9X SIDEWINDER CAT and Dummy Missiles

haha...Originally posted by twists:$1 million or $1 billion?
if 1 million...tink many ppl can afford 1 already....even better whn its 12 for 1 million... -

According to Wikipedia its US$1 billion. That's A LOT more than S$1 billion. Also, the proposed weapons and logistics package are said to be worth a further US$741 million.Originally posted by duotiga83:oops my mistake...is SG$1 Billion
