Defence-Technology Dudes

[Kunjungan ke Indo Defence Expo & Forum 2024] Sekitar dua minggu lalu, para kru Defence-Technology Dudes berkesempatan menghadiri Indo Defence 2024 yang diselenggarakan pada tanggal 11-14 Juni 2025 lalu di JIEXPO Kemayoran, Jakarta. ⬇️Sebuah utas🧵

The Rolls-Royce RB211 was a perfect athlete. A 70s technological marvel, this is the jet that almost broke Rolls-Royce, driving it to near bankruptcy. A broad menu of technological firsts were attempted in this program, including carbon-fibre fan blades (which Rolls-Royce subsequently backed away from). The RB211's design legacy was the fabulously successful Trent family of engines that has made RR the aerospace colossus it is today. Not bad for a half-century bet! But the biggest hidden design legacy of RB211's ambition is the addition of a 3rd spool inside the engine: A shaft inside a shaft inside a shaft, each powered by, and powering, a different part of the turbofan. The design & manufacturing difficulties of this architecture, still unique to Rolls-Royce, were legion, but it paid off: Not only does a third shaft allow you to run the big fan from its own dedicated low-speed, low-pressure turbine stages, but it also adds impressive modularity to the engine design. This allowed RR to scale-up and optimize the Trent family for new airliners with impressive agility, which in turn let them successfully slug it out with their far larger American competitor, General Electric. Modularity matters.

HGVs, place 😐 HGVs, Japan 😃 state.gov/japan-hyper-ve…

Senate give this morning the green light for the transfer of aircraft carrier ITS Garibaldi in favour of Indonesia. This is a turning point, because was indirectly linked to the DRASS deal with Indonesia, for the delivery of two SVD (DS8 for SF) and six high-tech DGK submarines.

Ground operation in Iran would be hell. Cheap FPV drones eliminate a lot of advantages that a developed military and well trained infantry such as American has. And it will be televised. I have been working with multiple units in Ukraine trying to minimize the impact of cheap fpv and bomber drones on the battlefield. We tried many things, from radars, shotguns, net guns, lasers, EW. Pretty much nothing works, there is no tech that can deterministically eliminate the threat. You can only minimize it, and we aren't talking about 80 percent mitigation, we are talking about 30 percent if you are lucky. Only physical barriers at the positions work effectively.

A sequence of images capturing a test detonation of the BLU-118B thermobaric bunker-busting bomb. The other image highlights its effectiveness against hardened targets such as caves and tunnel complexes, where its sustained blast pressure is designed to maximize damage in confined spaces. Interesting weapon system.

Where is Iran getting its high-res BDA? Check the Chinese commercial archive. 👇 Recent pulls show heavy 30-50cm optical tasking by China Siwei over regional US/Allied bases just this past week. The IMINT Pipeline: ➡️Unlike US private equity firms (Vantor), Siwei is a direct pillar of the PRC state (CASC/SASAC). ➡️They sell this data globally via SpaceWill, acting as the commercial storefront for China's state-owned satellite apparatus. ➡️SuperView Neo’s massive 42km swath width allows them to sweep an entire base or an underway SAG in a single pass. US firms are no longer the only game in town for 30cm spatial intelligence.

海上自衛隊 第1,2,3水上戦群 編成表 昨日に公開した第2水上戦群の反響が多きかったので第1,3水上戦群も製作しました。

Kami ingin membahas ini dengan lebih detail, sayangnya belum ada waktunya😅

"Tech tree" atau kecabangan ilmu mesin roket dan mesin jet sedikit berbeda, walau sama-sama termasuk hi-tech engineering untuk propulsi. Bisa membuat mesin roket (ada banyak jenisnya) belum tentu bisa membuat mesin jet militer (spesifiknya turbofan).

@sugondese6666 PAF kuat, yang untung juga Indonesia sebenarnya😂

jujur gwe pengen ini kejadian biar pinoy bisa "beneran" sombong 😭 kasihan AUnya dicengin mulu

Easy mode when they are used in a training environment. Employment of Switchblade 600 in Ukraine is far from 100% effectiveness due to EW, interceptors, and other challenges they face in an actual combat environment.

#DJMAX 밀리터리 테마로 작업에 그렸었던 KF-21이 마침내 1호기가 출고 됬네요 ! 작업 할 수 있어서 정말 좋았습니다 응원 합니다 #KF21 ! The KF-21 has finally been rolled out! I had the absolute pleasure of drawing it for a past DJMAX military theme, and I loved every moment of it

Saya paham ini niatnya mendorong kemandirian, tp kalimat "biarkan hasilnya buruk asal buatan dalam negri" Adalah suatu kalimat berbahaya.. ada nyawa operator yg di disregard, ada operational effectiveness yang menjadi pertanyaan , ada reliability issue yang bisa jadi bom waktu

Jika misalnya nanti China melampaui US dalam hal ekspor dan teknologi alutsista kemudian mulai memberlakukan aturan pembatasan ala ITAR, itu sah-sah saja dilakukan. Protektionisme teknologi akan selalu berdampingan dengan upaya pencurian teknologi hingga akhir zaman.

Indeed, parameter seperti ini adalah proprietary knowledge yang dijaga ketat bukan hanya oleh perusahaan produsennya, tapi juga negara asal perusahaan tersebut. ITAR ada untuk melindungi keunggulan teknologi US, walau dari sudut pandang negara lain ini merepotkan.

@inboundandhot TDD ini kebiasaan jelek suka nyolong konten orang lain, tenggelamkan saja😂

Kasi paham mint 👌🏽👍🏼

Mungkin perlu jadi perhatian bagi TNI dan Pertamina, terkait penjagaan sumber daya strategis nasional di tengah proliferasi ancaman serangan OWA drone👇

@fdenver12 Ikut litbang fighter gen 4+ sebenarnya tidak masalah, asal benar benar konsekuen dan all-in menyokong programnya. Bukan cuma pendanaan, tapi juga hal seperti efisiensi birokrasi, management oversight, litbang mandiri, konsolidasi indhan dalam negeri sbg subcon, dst.

@DefTechDudes Kita tiba" ikut development fighter gen 4.5 aja ga ideal, padahal idealnya step by step mulai dari trainer, light fighter baru gen 4.5 imho

Ya karena tidak ada centralized initiative dengan perencanaan yang matang. RE tanpa tujuan yang jelas tidak akan menghasilkan pesawat tempur lokal begitu saja. Apakah ada program litbang pesawat tempur dalam negeri? Tak pernah ada, mentok hanya studi LFX milik LAPAN.

Tanpa merendahkan LAPAN dan para peneliti yang melaksanakan studinya, studi LFX tersebut pun memiliki cakupan yang sangat terbatas. Bukan full-fledged national R&D program yang muaranya ditujukan untuk menghasilkan produk seperti JSF atau KFX. Wajar, anggarannya cekak.
