Hanwha Aerospace is a 2015 letterhead on a older Samsung machine-building line. Samsung Precision Industries (later Samsung Techwin) grew in the Yulgok force-modernisation and heavy-chemical industrialisation of the Park Chung-hee decades: licensed engines, then artillery, then a national howitzer that export customers would call K9 Thunder. In 2014-15 Hanwha -- Kim Jong-hee's explosives-and-chemicals chaebol, later chaired in public by Kim Seung-youn -- bought the defence-and-engine company. The name change is a chaebol story, not a clean birth.
This page is Korean industrial-military history for a Korean and a global reader: Agency for Defense Development (ADD) as the state laboratory cousin, Doosan DST and other land-system neighbours, and the 2020s European rush (Poland's framework headlines for K9 and K2) that put Changwon on English business pages. It is not a brochure, not a live order book, and not a how-to for K9, K2, engines, or any munition.
Scale is the smallest of the four industry files -- a national champion, not a 1995 US mega-prime. TechShift is mid because K9 and later K2/engine work changed what "ROK can export land systems" meant. Cultural memory inside Korea is jobs, conscription-adjacent pride, and air-show stands; in English it is still a 2020s discovery. Pair this file with the ROK military page and with Rheinmetall as partner-rival.

Deep introduction
A chaebol that bought a Yulgok factory line
Hanwha Aerospace is what happens when a 1970s state-led defence industry is later sold across chaebol families and then meets a European ammunition-and-artillery scare.
Yulgok roots
Park Chung-hee's Yulgok programme and the Heavy and Chemical Industry drive created licensed production and then domestic types. Samsung's precision works were one chaebol answer among several (Hyundai, Lucky-Goldstar / later LIG, and others).
Lee Byung-chul's Samsung is the ancestor politics of Techwin, not a gun lesson.
K9 as a national type
The K9 Thunder (service from 1999 in ROKA) is the public signature: a 155 mm howitzer that became an export object to Turkey (as a partnership), India, Norway, Australia, Finland, Egypt, Poland, and others in dated deals -- names and years as news history.
No firing table, no charge, no survey-how-to.
2014-15 sale
Samsung exited a defence line; Hanwha entered. Kim Seung-youn's public chairmanship and later Kim Dong-kwan generation headlines are family-firm politics. Doosan's land-systems pieces also moved in the same decade's sorting.
A sale is a political-industrial event in a conscript state.
Europe after 2022
Polish K9A1/K9PL and K2 headlines, plus Rheinmetall teaming stories, put the firm in the English Financial Times. This is budget history in Warsaw and Seoul, not a weekly tracker and not a production-rate leak.
TankK2 as a type-history cousin -- no layout lesson.
RheinmetallPartner-rival on guns, vehicles, and European volume.
Korean WarThe 1950-53 wound that Yulgok was later sold as answering -- a political memory, not a product demo.
Key terms
Yulgok
ROK force-modernisation programme name of the Park decades -- policy, not a shopping list to copy.
Samsung Techwin
The 1991-2015 name of the line Hanwha bought.
K9 Thunder
ROK 155 mm self-propelled howitzer -- export signature. Named, not instructed.
ADD
Agency for Defense Development -- the state lab cousin of chaebol works.
Offset / industrial participation
How import states, including earlier ROK itself, demanded local work -- a procurement term.
Changwon
The public industrial geography of much of this line.
From licensee to exporter
The arc English features love: a 1970s licensee becomes a 2020s seller. True enough as a cartoon; the middle was ADD, budgets, and failed programmes as well as K9.
Do not turn the cartoon into destiny.
Chaebol politics
Samsung out, Hanwha in: a family-firm market for a strategic industry. That is Korean political economy, not a footnote.
Compare BAE's privatisation and Lockheed's 1995 merger -- three bargains.
Europe as a late theatre
Poland and others are customers in a dated scare, not colonies and not a permanent "Korea wins Europe" headline.
Rheinmetall remains on the same map.

Frequently asked questions
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
What is K9 Thunder in this file?
A ROK self-propelled 155 mm howitzer that entered ROKA service in 1999 and later became the firm's public export signature. Named as industrial history. No employment or manufacturing content.
Why did Samsung sell?
Public file: Samsung's portfolio choices after years of being a defence-and-engine maker; Hanwha's bid to be the land-and-aerospace chaebol. A 2014-15 political-industrial event.
How does Yulgok relate?
Park Chung-hee-era modernisation and heavy industry created the supplier base. This is policy history, not a praise song and not a coup file (see korea-1979 for 12.12).
What is the Poland story?
2020s framework headlines for K9 and K2 as Warsaw rearmed. Dated news history. Not a live delivery tracker and not a how-to.
How does Rheinmetall fit?
Gun, vehicle, and ammunition-plant partnerships and competitions -- a two-firm European-Korean file.
Is this the same as Hanwha Systems or Hanwha Ocean?
Sister letterheads in a chaebol. This page is the aerospace-and-land-engine/artillery line. Do not collapse the group into one shop.
Is this a how-to?
No. No artillery, armour, engine, or munition guide. Encyclopedia of a firm and of ROK industrial policy only.
