Hot Take: Strategic Bombers are obsolete!!
#USAF & #Indianairforce engaged in #Copeindia2023 & the former bought #B1B and are making #B21. The #Chinese are building new H-6Ks. The #Russians are building new #Tu160. You ask, #εpsilon why do you think bombers are obsolete? Image
Coz, in a peer conflict, none of these will be used as strategic bombers as that role is behind them. These will be used as #Cruisemissile carriers that will never do old school bombing until all enemy AD is down. Pic credits: #Indianairforce Image
Look at #Russians for eg. In #Syria, they used #Tu22M as old school bombers as the AD threat was very low. In #Ukraine, these are launching missiles from well inside #Russian and #Belarussian territories. Image

Lets list in my opinion the worst decisions taken or nearly taken by largest navies around the world. #εpsilon Image
The #USNavy #Zumwaltclass destroyers were supposed to have #AGS capable of firing ultra long range 155mm shells, have no shells as they were canceled. Now, to re-add the X-factor the #USN is replacing AGS guns with VLS for upto 12 hypersonic missiles. Costing a lot of $$$$$$$$$s Image
Once the greatest #Navy on Earth, decided it was too great and powerful to have a ship mounted AShM. The #Brits decided #RoyalNavy could retire its #Harpoons without procuring a replacement anytime soon. Luckily , it didnt happen. This is why I feel #UK will cause #AUKUS to fail? Image

Lets do a short #T90 vs #T72 visual diff thread. #T90 is an evolution of the #T72 & was originally supposed to be called T-72U or T-72BU. Also, remember that early #T90S exported were actually #T72 turrets on #T90 hull. The pic is a T-90A Mod 1992 (feel free to correct) #εpsilon Image
But first, how do you know it is a #T90 or #T72 in the first place? Look at the wheels, it should have 6 road wheels with these spoke & cavity type design. If there are 6 cavities (pic 1), it is a newer #T72, if there are 8 (pic 2) older #T72. If there are 8, then confirmed #T72. ImageImage
#T90M's wheel cavities (also called indentations on all #T72 and #T90) extend till the rim edge instead of just short on older #T90A, #T90S and all #T72
Pic 1: #T90M without skirts, identations till wheel rim edge
Pic 2: #T72B3, identations just short of wheel rim edge. ImageImage

BOY! The amt of disinfo here can make it difficult for anyone to decide true & false. Given the conflicts that are raging & political posturing between #US & #China #US & #Russia #UkraineRussiaWar #RussiaUkraineWar #India & #China I have a unique thread #εpsilon Image
No. 1, The event eg. something happens btw 2 countries, trust in this order and identify overlaps. The overlap is usually true.
1: Unedited videos of same event, multiple angles
2: Unedited pics of same event, multiple angles
3: Directly or indirectly corroborated by both
eg.... Image
Eg 1. Moskva sinking
3a: #Ukraine claim, Moskva sunk by AShMs
3b: #Russsia claim, Moskva sunk by fire & storm
2: Pics of Moskva with sooty hull, big black marks/holes on the hull near water line away from openings.
1: Video of Moskva showing all in pt 2.
Conc: Moskva sunk by AShM Image

#Whatwerethedesignersthinking when they put the radars for Trophy APS on the front, on top of the main armor. Now, I love #Leopard2, IMO it is the best tank in service today. #Germans did nothing wrong, except these radars. #εpsilon Image
The frontal 60 degree arc is said to be most suceptible for enemy hits and the #Germans placed the critical radars on the front armor. Makes no sense at all. Look at #Americans on their #M1Abrams. The radar is off to the sides. It is still exposed though. Image
The #Israeli #Merkava has its #Trophy pointed more outwards but again away from the primary frontal protection. Its the #Germans who have a pretty bad design for what is a safety critical system in combat and will only gain importance. Image

This is a opposite #whatwerethedesignersthinking thread. The #Russians built a 5,000 tonne frigate that has more missiles than several larger contemporaries. It has 16 AShMs VLS (2 3S14 8 cell UKSK modules) and 32 Redut SAM VLS for 9M96E 40 km and 9M96E2 120 km missiles. #εpsilon Image
My very scientific metric 115 tonne per missile (I know it is not scientific, just a fun metric). For eg. #Indian #Kolkataclass is 154 tonne per missile, #British #Daringclass is 168 tonne per missile. But, those are destroyers and have larger stores for longer deployments Image
It is funny that these frigates have the same peer armament as #IndianNavy MF-STAR destroyers with equally potent AD & AShMs at 2/3rds the displacement which limits endurance for this #Russian ship. The Gorkys are based on elongated Krivak/#Talwarclass/Admiral Grigorovich hulls.. Image

My Indian followers,#Russians have benefitted a lot from you guys designing and purchasing #Russian origin gear for them to swoop in and buy some you guys paid to develop or revive. Exhibit A: Su-30MKI becomes Su-30SM. #εpsilon ImageImage
There are two distinct #Su30 lines, #Indian #Su30MKI at Irkut plant and its derivatives and #Chinese #Su30MKK at KNAAPO plant and its derivatives. The Su-30SM, bought in nos is from MKI lineage. To be fair #Russianairforce also bought 18 Su-30M2s to keep KNAAPO busy before #Su35S ImageImage
Exhibit B: MiG-29K operated by the #IndianNavy made sure that the #Russians can buy a few for themselves after the #Indian production run was done. Else, they might have stuck to upgrading their Su-33s in the long run. ImageImage

Our previous threads on naval vessels have highlighted the lack of AD on #Pakistan's #Zulfiqarclass, lack of any missiles on #Indian #Kamortaclass. But does an ideally armed vessel for its size look like? The #Russian Stereguschchiy class says hi! #εpsilon Image
These are sadly the only two blue water capable naval surface vessels #Russians have been able to produce in numbers. With 8 (including related Gremyashchiy) in service and 20+ planned, these will be the bulk of the #RussianNavy fleet Image
For a 2,000 tonne corvette the Stereguschchiys have 16 SAMs derived from the S350/S400 9M96 family of missiles capable of 40 km to 120 km engagement zone. The lead ship lacks this and has a Kashtan CIWS on the bow. They carry 8 Kh-35s as well. Gremyashchiys have a UKSK module... Image

#Whatwerethedesignersthinking when they designed the INS Kamorta as part of #Kamortaclass of ASW corvettes for the #IndianNavy . These vessels displace within 500 tonnes of #IndianNavy's own #Talwarclass #frigates and #Russian Admiral Grigorovich class #εpsilon Image
I have not seen a lot of coverage of these essentially frigate sized OPVs of the #IndianNavy and hence wanted to do a comparion. These vessels have no cruise missile VLS cells or any Air Defense VLS cells. She just has 2 RBU-6000s and a torpedo launcher for sub hunting. Image
So the #IndianNavy took an average of 8 years to build each one of them and 9 years after the lead ship was commissioned, she doesnt have a VDS (Variable Depth Sonar)/ TAS (Towed Array Sonar), essentially for what is officially an ASW corvette. Image

Had to use this hilarious picture!! The #AUKUS program doesnt instill much confidence in me personally. The program was supposed to bring together the #USNavy , #RoyalNavy and the #AustralianNavy to build a #Nuclear sub fleet. What about #IndianNavy? #εpsilon Image
The #UK in post #Brexit is notorious for armed forces cut that make little sense. There were rumors that they might cut the fleet size of #Astutesubmarine and give 2-3 to #Australia in #AUKUS. The current plan hinges a lot on #UK being not #UK . Image
The US is letting go of its 3 #Virginiaclass production slots to sell the boats to #Australia in 2030s. This will be followed by #SSNAUKUS to be built from mid 2030s to 2040s. This program is highly dependent on UK not being UK and funding the new SSN development. Image

Looks like my #IndianNavy missile test thread blew up so, a follow on thread on its sister force #IndianAirForce . The collective west, coming out of the Cold War expected the #IAF to be a more Soviet aligned force. #Su30MKI #F35B #TROPEX #εpsilon #MiG21 #MiG21Bison #Mirage2000 Image
The #IAF however has the unique perspective of operating the top western and the top #Russian of alternate &/or every generation egs Hawker Hunter (credits on pic), #MiG21, #MiG29, #Su30MKI, #Mirage2000 #Harrier ImageImage
Each fighter brings in with it, performance numbers but also tactics and maintenance regimen and India can tap into #Russian or #British ideas and pick and choose what works the best. Image

BVR (air and sea) is not as simple as it sounds, wondering why I am posting a picture of MiG-21? Answer is below.
I see a lot of takes on the internet where a country A has a 150 km missile and a country B has a 120 km missile so A is better than B and the case is closed #εpsilon Image
Imagine a MiG-21 with its small nose cone radar with an R-77. Can the radar even detect a small RCS target at that range? Rafale, Typhoon, J-20 and even smaller jets like MiG-21 itself might not be an accurate fix at those ranges. Throw in jamming, ground clutter, fog of war and. Image
At those ranges, how sure you are that the target is what it is? Plus, there are other factors
1. Is the BVRAAM Active Radar Homing or Semi-Active (most modern ones are Active, so one problem solved)
2. RWR load out of the target aircraft, jamming suite, countermeasures suite etc Image
