Purbaya Approves Purchase of Chengdu J-10 Fighter Jets, Worth US$9 Billion

Minister of Finance Purbaya Yudhi Sadewa confirmed that the Ministry of Finance has approved the budget for purchasing a fighter jet or fighter jet from China, the Chengdu J-10.

Purbaya said the budget for purchasing the Chinese-made fighter jets reached US$ 9 billion.

"US$9 billion, if I'm not mistaken, or more. I forget the exact figure. But it's been approved, so everything should be ready," Purbaya emphasized when met at Wisma Danantara on Wednesday (10/15/2025).

Purbaya added that he had to double-check the purchase of the fighter jets. Although the budget had been approved, he admitted he didn't know when the fighter jets would be imported.

"What was mentioned should have been included in the budget. But I'm still double-checking whether he plans to import again next year or when," he said.

Edit: it seems like the deal may not be worth 9 billion, but rather that is the finance ministry's budget. Here's the interview at 2:00:

(Maybe someone here who speaks Indonesian could help us better understand what’s being said)

9 billion US Dollars are almost Indonesia's yearly defence budget, this has no way to be serious.

Indonesia's defense budget is way low compared to its gdp. They can increase it much further. Prabow seems to be moving towards a higher defense buildup

Sorry guys, I already know there's a huge differences in J-10C and Israel's Lavi project, especially in what matters like the electronics, subsystem, the engine...etc. But I remember there was some differences in the airframe and its design but I don't have the expertise to know it buy just looking at it, and I can't find the posts about it.

If someone can mention them again or give me some references it'll be very helpful.


Edit: weirdly i found a lot of content in Iran's forum about the topic, but still if some one more detail & coherent it'll be helpful.

The J10 was based largely off the Lavi. It's not a secret.
Israel and China had a relatively close relationship back in the 80s and 90s.
The J10C and newer variants like DSI etc. were mostly of Chinese designs.
It's no different than a J16 of 15 based of off the Flanker. The only difference is the Lavi program was killed at the very end even though a couple of prototypes were already flying.

9 Billion is the procurement budget for Indonesian defence next year. For J-10, rafale, kf-21, naval equipment, etc

They are optimized for different roles and flight regime. Lavi had swept wings and close coupled canards. It was supposed to take more of an air to surface role and optimized for lower speed. J-10 is optimized for fighter interceptor role so it uses medium couple canards and delta wings.

A bit of schadenfreude re Lavi, paid for by the americans (because there is no way the israelis could even afford to build the prototypes- i do have a passing knowledge of Lavi history), mostly american technology (because certainly back then most of the israeli technology was pilfered from their american sugar-daddy), only for the mischievous israelis to share it with China, becoming the stepping stone to the J-10 which is today one of the nemeses of the american (and not only) military. Gotta love the irony.

Much easier said than done. By default, the defence budget grows when the national economy grows and taxation revenues with it. Increasing the defence budget above the rate of economic growth requires increased taxation, changing the distribution of taxed revenues, or taking on more debt, with each path carrying political costs and risks. In August there was civil unrest in Indonesia connected to perceptions of parliamentarians unjustly increasing their own privileges. Acquisitions such as fighter jets and high-end warships may be defensible in military and national interest terms, but they also gratify only narrow constituencies, even within the armed forces. Hence the vulnerability of such projects, as they approach the point at which funds must be definitively allocated and disbursed, to being sidelined in favour of more politically pressing priorities.

The J-10 was based on the cancelled J-9, which was designed over a decade before the Lavi ever flew. Comparing it to the Flanker variants is particularly egregious, too: the J-16 and J-15 have essentially the same overall airframe as their forebears (albeit with significant upgrades), while the J-10 is significantly larger and heavier than the Lavi, has a different canard arrangement, a more powerful engine, a completely different gun setup, different intake geometry, lacks wingtip AAM pylons, etc., etc. Even if they benefitted from IAI's data in some way (and to my knowledge there's no paper trail for that as there is with the J-15, for instance), the sheer scale of the differences make it an entirely new aircraft in a way that the J-15 and J-16 aren't. If it really is a copy, why change so much?

This is such a classic (almost a meme) misrepresentation of J10 development history that I want to believe you are just trolling.
