2025 Victory Day parade thread (workup, 3rd Sept)
- Thread starter Blitzo
- Start date
I think those insane western military fans they mentioned probably aren't referring to SDF users. After all, members here have already seen most of the parade gear that's been unveiled.
The "funny thing" about SDF users of ethnic Chinese descent is that many of them are considered foreigners in China, yet Chinese in the countries where they reside.
According to Guancha trio, sadly probably No. However, rumors suggest reorchestrated renditions of timeless classics are coming (like 在太行山上).
I'm a simple man: I like big missiles, I like big trucks.
The list is ordered from "marginally plausible" to "makes Western defense watchers go [head explode emoji]"
You are right but there is one area where air breathing is better - for reusable craft. Yes the conversation was about missiles, expendable ordinance but there is certainly a purpose to refine engine technologies for hypersonics. In this regard, China has test flown many variants of rotating detonation engines, oblique detonation aka sodramjets aka schramjets and of course various TRCC and TBCC combined cycle type engines which probably was aided in achieving hypersonic speeds by way of staged and discarded additional rocket boosters and/or air launching.
Since combined cycle engines, rotating detonation engines and schramjets are all much more advanced and complex engines to master than scramjets, the only purpose of applying scramjets is on single use HCM. Scramjets are considerably cheaper and mechanically simpler than these four other forms of hypersonic air breathing propulsion. HCM would potentially make use of rotating detonation or schramjets but certainly not any combined cycle. It just wouldn't make any sense to especially considering there isn't truly any performance advantage with combined cycle engines for single use missiles. Combined cycles offer greater flexibility and potentially also safety/survivability for reusable hypersonic vehicles though.
Lol pulse detonation is shit.
China has mastered rotating detonation... that means continuous detonation. Several test flights from even public research institutions/universities for years now. It's not even a secret. Chinese military is 10 years ahead of Tsinghua University rest assured.
Pulse detonation lol... what is this 1997? To China's top tier ring, that garbage is about as "exotic" as a lawn mower's piston engine these days.
The reason why DARPA was interested in HTV-2 was because HGV is really at the highest end of long-range fires. Gliding warheads can achieve very high accuracy and maneuverability because it's steerable all the way to the target and can extend its range by gliding. There are many technical issues with scramjet missiles in that its really hard to actually get good performance on it - X43A and X51A data was quite conclusive on this matter.
Both systems require initial acceleration with a solid fuel rocket anyway. The US can detect all missile launches instantly (SBIRS, HBTSS) and then just cue a ground or ship-based radar so if the goal is to evade or shorten the kill chain, it won't work. The aforementioned capabilities are what is attractive about gliders.
Check out this with the designer of HTV-2 and he has some insights into China's current systems, esp. strategic gliders, and what it takes to defeat it. It's already more or less at the highest end of what is possible.
This timestamped clown in the YouTube video is peddling the delusion that if the US just prevents China from invading Taiwan for the next few years, China will economically collapse and no longer be able to afford space and military investments. He also goes on to explain that the US achieves more with two launch sites and two vehicles than China does with more than a dozen launch sites and vehicles. This is a sales pitch for more funding from the US government. He's just like all the other snakes angling for funding and selling dreams of American dominance. He's definitely not talking like a real engineer or designer. Instead, he's talking like a politician or a sales rep. Thank you for sharing nothing of value.
There's a reason "Punchbowl News" has 6k subscribers and this video has 429 views over 4 months. ULA paid them to provide a platform for pitching that the US government should do even more business with them. Then they paid a few senators to do some cheer leading before Tony Bruno goes on stage. None of this is serious analysis. It's a tiny part of a larger lobbying campaign.
In August 2014, Bruno left to become the president and chief executive officer of (ULA), a joint venture owned by and . Bruno's appointment came as ULA was facing increased competition from newer entrants into the space launch industry, especially from with their rocket, in addition to political pressure from the to stop purchasing the -made rocket engines for use on the . Under Bruno's leadership, ULA responded to these issues by announcing , a new rocket building on the technology of Atlas V and , using the engine developed by .
Despite achieving certification, military officials have expressed sharp dissatisfaction with Vulcan's performance during its protracted development. In written testimony to the in May 2025, Major General , said that the program had performed "unsatisfactorily" in the previous year. He noted that the slow transition from the retired Atlas and Delta vehicles to Vulcan had delayed four national security launches, hindering the completion of Space Force objectives. Purdy said that, moving forward, United Launch Alliance must "repair trust" and demonstrate greater accountability.
In other words, ULA is failing to meet military expectations and is desperate to sell the story that they are winning, the US is winning, the US will win, and ULA is key to that. And please keep giving us lots of money, more and more.
