The reason Rosatom is the ONLY firm building in Turkey is b/c Rosatom is an entity of the Russian government, subsidized, and willing to take a loss (and even at that they are trying to sell stakes to capital raise to offset losses).

The limitation on US investment in the Turkish nuclear sector is the BOO model. Not a lack of interest historically from Westinghouse et al. It is simply too capital intensive for private entities to finance a reactor based on a fixed price of kWh purchase agreement over 20+ years.

I'll just add: It is not at all odd to use a foreign engine in your prototype, or an engine not designed for the jet. The F110 isn't a bottleneck to Kaan, per se. So its largely irrelevant IMHO.
aaronstein1.bsky.social
I wasn't making it up:

US won't sell F110 w/out the F-16 and cannot sell F-110 to SSB w/out CAATSA being resolved. Can't resolve CAATSA w/out S-400 compromise. Tr also cannot "rejoin" the F-35 consortium. It can purchase F-35 but only w/ compromise on S-400. www.middleeasteye.net/news/turkey-...

This is why F16 talks were paused until F-35 is resolved. The entire bilateral relationship is frozen in 2019. Nothing has changed.
aaronstein1.bsky.social
F16 was paused (on the request of Ankara) because RTE wants the F-35. He wants the F-35 for regional prestige and to keep up with/ Greece/Israel and b/c of lost cash on the contract abrogation stemming from S400. Best case is Tr compromises on S-400 and can "buy" the F35. But cannot also afford F16

Turkey may drop US F-16 purchase in favour of acquiring jet engines
Ankara could buy parts instead of new aircraft in bid to accelerate fifth-generation Kaan warplane project

I'll just add that airport sightings are often fraught, with mixed reporting. The US has a single database. Don't know about the EU. But "large drones" need not be anything outside of the personal hobby class.

Good example is what happened in both Germany and in the UK at Lakenheath.
aaronstein1.bsky.social
I mean that is the story of the Cold War. People should familiarize themselves with how many times the two sides did shoot the other down. Mostly USSR shooting down US/NATO kit.
aaronstein1.bsky.social
The US is hamstrung in its response b/c of competing authorities, the potential danger to civilians, and even Article IV constitutional protections (jamming a drone is considered an illegal wiretapping in certain instances). I imagine EU has similar issues; www.fpri.org/article/2025...

We @fpri.bsky.social just finished a large study on drone incursions in the US. Most are accidents. Yet, proliferation of UAS has created an exploitable environment for malign actors seeking to conduct close target reconnaissance, or potentially even kinetic attacks against critical infrastructure.
aaronstein1.bsky.social
That was different context. I think comparing NATO Air Policing mission in countries bordering Russia w/ the extreme deficits EU nations face in defense vs a Su-24 shoot down in Syria w/ mixed outcomes is just apples to oranges and extreme fallacy.
aaronstein1.bsky.social
The Russians and Americans would fight a lot over Syria independent of anything Turkey was doing. 2017 was a particularly feisty year. Many near misses.
aaronstein1.bsky.social
No they got more aggressive because Turkey shot down their jet.
