Legal Basis for Designation

Two independent grounds. Either is individually sufficient.

Primary Ground

EO 14024 — 50% Ownership Rule

OSK (direct parent) is OFAC-designated under EO 14024. Under Section 1(a)(iv), entities owned 50% or more by a designated person are automatically blocked — no additional nexus or discretionary determination required. The entity name contains 'ОСК', making the ownership relationship a matter of public record.

→ Automatic — no discretion required
Independent Ground

EO 14024 — Defense Sector Prong

Section 1(a)(i) covers persons operating in the defense and related materiel sector of the Russian economy. Designing SSBNs carrying Bulava ICBMs and SSGNs delivering Kalibr cruise missiles into Ukraine is unambiguously within scope. This ground survives independent of the ownership chain.

Discretionary — defense sector determination
EU Ground

EU Reg. 833/2014 / 269/2014

OSK is listed under Council Regulation 833/2014 Annex IV. As a direct OSK subsidiary engaged in defense-sector activities, ЦКБ МТ «Айсберг» meets criteria for listing under Article 1 of Council Regulation 269/2014. Requires Council act — mirrors OFAC ownership logic.

UK Ground

Russia (Sanctions) (EU Exit) Regs 2019

UK OFSI status not yet verified. Mirror designation recommended following OFAC/EU action. OFSI typically acts within 30–60 days of convergent OFAC/EU designations on Russian defense entities.

Intelligence Gaps

Two open items. Neither is blocking for OFAC or EU submission.

!
UK OFSI sanctions status not verified
Cross-reference against OFSI consolidated list XML not yet performed. Non-blocking for OFAC/EU referral. Estimated 30 minutes to close via OFSI XML dataset.

Submarine program contract numbers not extracted from case text
Project 955 / Project 885 specific contract references not yet extracted from sudact.ru case text. Entity-level identification is sufficient for designation — program IDs strengthen narrative only. Estimated 3 hours via case text analysis.
