Agreed sir

Ghanta
Pl-15 I a match to astra mk2 as it falls same category
Mk3 is class apart
Common sense
Mk2 matches with pl-15 wrt range also
Mk3 will be of meteor class

How far are we from Mk2 and Mk3?

How far are we from Mk2 and Mk3?

Woh pata nahi
Depends on testing and result of it
If failure occurs then time will be more
Who knows the timeline but mk2 atleast 5-6 years far according to me

Don't think so it will be mass produced in 1-2 years

P15 & astra mk2 not same, and astra can't match p15 range or nez. astra mk2 similar to aim 120d.
Both astra mk2 & aim 120d better than pl15e[with aesa seeker] but can't match pl15. Pl 15 heavier & big compared to akash & aim120 & developed to counter meteor.

How far are we from Mk2 and Mk3?

Astra Mk2 look 3-8 years away from IOC.
Astra Mk3 we can say would take 5-15 years away from IOC. Not a lot information is about Astra Mk3.

Those numbers are completely false bro regarding pl-15
Yeah range might be more than mk2 but only by 20-30km max
Export variant has range of 145km

Which nos ?
Pl 15 developed to match meteor, and better than aim120d [range/nez], and USAF & USN urgently developing new aam to counter pl15.
Unknown - astra mk2 range/nez/specs etc & same goes to pl15.
USA/Japan etc r&d ing new aam to counter pl15 including future meteor.
Chinese rocket propulsion and seeker tech are best [thanks to industrial base/theft/espionage/buying etc] but they lack behind algorithms/software, but they are catching up very fast.
Export version is a highly downgraded version. Pl 15 is second best aam after meteor with best seeker, similar range and less nez - considering US and its allies, UK/USA/Japan started new aam to match/counter pl15.
Chinese ramjet tech sucks, hence they r&d aam using best tech developed by them, and pl15 developed using aesa & rocket motor, techs which is familiar to them.

Ir can't be close to meteor or mk3 as its dual pulse rocket motor has disadvantages against ramjet
It can increase range but can't be effective like ramjet missiles
As I said range is not everything definitely pl-15 will be 20-30km more than mk2
If export variant is 145km then their missile could be of 180-190 km according to some estimates
Mk2 will have range of 160km
Mk1 itself have range of 110km single pulse

Size does matters. Ramjet need motor to kick start. Meteor having extra weight due to integrated motor and propellant and mk2 don't having any extra weight, same goes to d & pl15.
The exact range of meteor, aim 120 d, pl15 unknown. In the case of pl15, its bigger, not hypersonic, using aesa tech, and having long range. Chinese says second best aam by nez after meteor. US believe pl15 superior to aim d. Even in your theory pl15 range come close to 200 km. Since pl15 developed to counter meteor, sites copy & paste meteor range into pl15 spec. Range will be less than meteor, but greater than both aim 120 d & astra mk2. Mk2 range around 160km, or greater, but lesser than pl15 and less weight compared to pl15.
pl15 not like pl10, which is similar to aim 120c, range around 110 km, means its entirely new missile unlike aim 120d.

 

[Chinmoy]

Wait, I must be blind because I see absolutely no physical difference between Mk1 and Mk2 ? I initially thought Mk2 must be thicker and longer (that's what she said), but after a side-by-side comparison between Mk1 and Mk2 launches, they have practically identical bodies.

But that means Mk2 might only have a marginal improvement in range due to improved rocket propulsion.

Why you think it would be anydifferent?

Just compare Derby and Deby-ER. Both are dimensionally same with only the difference in propulsion.

The touted range of 160km for Mk-2 is almost a 50% increase over the previous range. This range increase is too ambitious to achieve (in my opinion) just by improving rocket propulsion, without increasing the actual fuel content.

Second, Astra is by far the only new-gen. BVR with such a high surface area fins. The central support fins are actually massive and should contribute to significant drag at supersonic speeds. Not only those massive fins will cause more drag, but will make the missile lose energy faster at an endgame chase, where sharp turns will cause those massive fins to act like giant airbrakes.

Overall, the initial render of Astra Mk-2 with frontal canard fins would have been the predicted design choice.

Max range of Astra Mk-1 = 110 km
Max range of Astra Mk-2 = 160 km (not official)

Change in % = 45%

In case of Derby.
Max range of Derby = 50 km
Max range of Derby-ER = 100 km

Change in % = 50%

So you could see that the result of using dual pulse rocket motor is same in both case. Dual pulse rocket is used for the specific purpose to get maximum thrust during the endgame. Now if you think Mk-2 with its wings will not be effective in end game maneuvers, then it means Mk-1 is much more ineffective.

 

[Dark Sorrow]

Does anyone has idea why don't we use the smokeless propellant developed for Astra into SAMs like Akash-NG or QRSAM?

Derby range is approx 50km while dual pulse derby ER range 100km plus . They are identical in shape and size . Its due to optimal thrust control due to dual pulse .

50 to 100 is a 100% increase.. This actually makes your argument stronger.

I would like to add due to dual pulse rocket motor less energy is wasted during initial rocket burn.

Hmm, that makes sense. Any studies/explanations which show how dual-pulse rocket motor increases range significantly ?

Now if you think Mk-2 with its wings will not be effective in end game maneuvers, then it means Mk-1 is much more ineffective.

Yes, it will be more maneuverable but will lose energy faster.

I would like to add due to dual pulse rocket motor less energy is wasted during initial rocket burn.

Explain.

Anyway +-30-40km I not that significant
Mk2 and pl-15 fall in same category
