Tats is e antenna for e EPS-3000 Elisra self-protection suite

When e AMRAAM-D comes out, we might be using Meteor

Sepecat SG

Assuming the Meteor gets qualified on the F15 & thats a big assumption.

spartan_6 SG

There why it "might"

LOL. increasingly turbulent my foot.

R e F-15SE suitable 2 our needs?, cos i was thinking giving e proximity of neigbouring country their fighters would most likely be aidded by ground-based radar which can detect e Slient Eagles also aircraft like SU-30 has IRST from wat Boeing say e Slient Eagle is not stealth in e IR [email protected] long range can IRST detect them?

Shotgun SG

Strictly speaking, no "Stealth" is totally invisible to radar or infra red search n track sensors. Its rather a matter of "when" the radar or sensor is able to do so.

Being able to delay detection increases the probability of seeing ur enemy and shooting them first. Achieving the first look, first kill is very much part of most air forces' air combat doctrines.

Ya,@ wat range can e F-15SE be detected in such a situ will justfiy if they r worth e cost

Singmarine SG

I know there are several questions why the F15 is selected over the typhoon or rafale? F15 is not a new generation aircraft compared to typhoon or rafale.

I also have shock when I know Mindef selected the F15. Perharps some reasons

Avonics
Allows customisation from US our our allies.

Politicial driven
British has betrayed Singapore before in the 1960s while France normally yield to pressure from other countries-See 6 Day war In times of war, u have to make sure that your military logisitics are replenised as there will be high attrition rate. So which country do u think is likely to support Singapore in any conflict?

Cost
seems F15 is the cheapest among 3

Other than the obvious political rationale, just ask yourself: Would you buy a machine that only a handful of others own and operate? The new generation warplanes have not proven their performance nor sustainability. Many countries operate F-15s and it becomes easier to source for spare parts, facilitate upgrades, trade expertise, etc.

Many of the SAF's purchases are also strongly influenced by a certain other small country.

To add on, when I was in poly, a lecturer who was from the air force previously told us that just get two F-16 engines, prop them into an F-15, and the F-15 can fly.

Also, another lecturer said that many of SG's planes (like the F-16) were from the US, and thus the units of measurement in maintenance manuals and the like are all in imperial units (such as inches). It'll be the same for the F-15, thus avoiding the kind of confusion or errors that would otherwise be had if our Air Force techs need to work on a plane from, say, Europe, which would use SI units such as millimetres.

Correct me if me wrong. =3

Ya,@ wat range can e F-15SE be detected in such a situ will justfiy if they r worth e cost

None of us here can tell you that range. I doubt no one can give you an absolute number especially when it comes to detection ranges.

Detection range varies according to the ability of the radar, output, target aspect, radar cross section just to name a few.

As I mentioned earlier, its not about being totally invisible, but rather decreasing the range which the offending radar can detect and effectively employ weapons against it. This allows the Silent Eagle with a more advanced radar to achieve a better launch window to employ its own weapons while staying out of the enemy's reach.

As for the F-15 w/ 2xF-16 engines, thats largely correct. The current F-15SG models is using engines that are also used in the Block 50 models of F-16s in the USAF.

I think your lecturer is in a better position to comment on these stuff than most of us can! =D

spartan_6 SG

haiz, im not trying 2 found out e range wat i means is e RSAF has 2 find out @ around which range zones r they likely 2 be detected given above situ will most likely affect if they r suitable for our defence needs

weasel1962 SG

Irrelevant to know what range. The RWR should be sensitive enough to detect when the aircraft has been detected at whichever range it should be. The point is whether there are sufficient counter-measures to handle a detection and the F-15SG certainly has sufficient ECM and ACM capability for that purpose.

It is easy for an aggressor to under-estimate an old frame and that's been the SAF approach with the F-15, subs, MBT and other future acquisitions.

The F-15SG is a capable aircraft that exceeds the capabilities of all other aircraft in the region in the dimensions in which the SAF will conduct a war in.

Those dimensions includes range, power, detection, avionics, protection, pilot training, serviceability, munitions and delivery rates. And importantly, surprise surprise, its getting better with new capabilities being added on.

That's not to say the competing aircraft aren't capable. But in the context of what SG requires, just not as capable. Even the F-35 cannot compete on certain roles that the F-15SG excels in and that's why LM has focussed some effort in debunking the F-15SE effort.

spartan_6 SG

Can an aircraft avoid detection by enemy's RWR by not switching on it's radar but instead launch it'smissile using data provided by external platform thru data-link then wait till last min then switch on it's radar? cos missile like AMRAAM has mid-course up-date

spartan_6 SG

I personal feel e JSF is an aircraft tat trade-off 2 much for stealth

38 SG

An AESA radar like APG-77 of F-22 with LPI function has a high chance to elude enemy RWR’s detection. By the way, if fighters only passively receive guidance from AWACS and without their own Fire control radar on, it’s possible for the fighters approaching the enemy without alerting them. But end of the day, it still has to switch on its own FCR to lock on the target.

AIM-120D has 2 way datalink, so it’s possible for one fighter with its radar on can guide AIM-120D fired from another friend fighter without radar on. provided all platforms are in same co-ordinate system and have a "broadband" datalink among them.

weasel1962 SG

The early APG-70 of the F-15s already had LPI mode so its not really a new concept. The difference is that later AESAs allow continuous tracking without triggering the RWRs. From my limited understanding, this is achieved through low power, freq hop, etc. So there is no issue at least at this time of having secondary guidance + terminal guidance is "fire and forget" for the AIM-120.

IR missiles don't need tracking but sensitivity is an issue for long-ranged IR missiles.

Suk radars light up like christmas trees and they aren't aesa which suggests same problem with phased arrays.

---------------------------

F-35 isn't so much as trade off for stealth as designed for stealth. Even the -B version has more range without tanks compared to the F-16 with tanks, carries as much munitions internally as the F-16 with tanks, whilst still enjoying stealth with greater performance from higher thrust engines with higher TW rating, better avionics, internalised systems and capability for upgrade.

If the F-16 could fulfil the role today, its steps up with the F-35 (any version).

Its easy to say the F-35 could carry more, be faster etc. The limitation is always the engine ability and 2 would be required for better performance. That would be the F-22 with correspondingly greater cost.

spartan_6 SG

All fighter designs r a sort of compromise, u have 2 trade-off something for something, an aircraft tat excel in all areas, it compromise is it cost. So it really depend on wat a nation really needs it aircraft 2 do
