Who owns TAIS? The consortium’s partnership structure
Quick answer: Who owns TAIS? TAIS Shipyards is a privately held consortium in which Anadolu Shipyard (ADİK), Sedef Shipyard and Sefine Shipyard hold equal shares. At the 2017 founding there were five partners; İstanbul Shipyard and Selah Shipyard transferred their shares to the remaining partners in June 2019. The official website publishes no name-level information about the consortium’s corporate officers, so instead of personal profiles this file documents the ownership structure and the identity of the three member yards.
Ownership structure
| Period | Partners | Share structure | Source |
|---|---|---|---|
| 2017-2019 | Anadolu, İstanbul, Sedef, Sefine, Selah | Five partners, equal shares | Defence Turkey |
| After June 2019 | Anadolu (ADİK), Sedef, Sefine | Three partners, equal shares | Defence Turkey, company website |
According to Defence Turkey magazine’s report on the consortium’s founding, five shipyards established an equal-share company to combine forces in naval tenders and to approach foreign markets under a single brand. After the two founding partners left in 2019, the structure was streamlined to three partners. Today the official website’s partners page lists only the Anadolu, Sedef and Sefine yards. Beyond the equality of the three partners, further detail on the current share distribution is not officially disclosed.
Anadolu Shipyard (ADİK)
Operating in Tuzla, Anadolu Deniz İnşaat Kızakları (ADİK) is the partner that carries the consortium’s amphibious ship and training ship references. The Turkish Navy’s Bayraktar-class tank landing ships, TCG Bayraktar (L-402) and TCG Sancaktar (L-403), were built at this yard. The yard also delivered two cadet training ships (QTS 91 Al Doha, QTS 92 Al-Shamal) to the Qatari Navy. Construction of TCG İzmir, second ship of the İstif class, was likewise carried out at ADİK; the program details are in the İstif file.
Sedef Shipyard
Sedef Shipyard in Tuzla is the yard that built Turkey’s largest warship, the multipurpose amphibious assault ship TCG Anadolu (L-400); the ship is based on a Navantia-licensed design. In the İstif class, TCG İzmit (F-517) was built at Sedef, and according to Army Recognition the sixth ship of the series, TCG Karadeniz (F-520), was also launched at this yard in 2026. The yard’s amphibious experience is covered in the amphibious platforms file.
Sefine Shipyard
Sefine Shipyard, based in Yalova, carries the consortium’s logistics ship reference: the underway replenishment combat support ship (DİMDEG) TCG Derya was built at Sefine under a contract signed with the SSB on 28 June 2018 and delivered to the Naval Forces on 19 January 2024. In the İstif class, TCG İçel (F-518) fell to Sefine’s share. The catalog counterpart of the replenishment ship line is examined in the FRT-200 file.
What the consortium model is for
Naval tenders can reach scales that exceed a single yard’s slipway capacity, bonding power and engineering staff. The consortium model is the tool for clearing that threshold: the partners bid on large programs as a single legal entity, distribute the workload across their facilities and combine their reference lists. The İstif class, with three yards each building one ship simultaneously, became the model’s first major application; in the Indonesia agreement the same umbrella served as the signing party of an export structure with a financing partner.
What is known about the management?
The names of TAIS’s board chairman and general manager cannot be confirmed at name level on the official website or in accessible independent sources; this information is not officially disclosed. Executives of the member yards occasionally speak for the consortium in the trade press, but single-source statements were not used as personal data in this file. The consortium’s public-facing representation runs through exhibition appearances and signing ceremonies: the Indonesia frigate agreement of January 2026 was signed on TAIS’s behalf at the DIMDEX exhibition; details are in the export file.
Frequently asked questions
Is TAIS state-owned?
No. It is an equal-share partnership of three private shipyards, acting as the private-sector contracting party with the SSB and the Ministry of National Defence on military projects.
Which founding partners left?
İstanbul Shipyard and Selah Shipyard left the structure by transferring their shares in June 2019, according to Defence Turkey.
Who is TAIS’s general manager?
The official website publishes no executive names; since no current name could be verified through two independent sources, this information was treated as not officially disclosed.
Do the member yards work outside TAIS?
Yes. All three run civilian shipbuilding, repair and their own military contracts under their own legal identities; TAIS is the umbrella established for joint projects.
How are the shares distributed?
According to open sources, the three partners hold equal shares. The commercial-registry detail of the ratios is not officially disclosed.
