SUNJIN ENTECH CO.,LTD.

SUNJIN ENTECH CO., LTD. specializes in the repair, maintenance, and logistical support of U.S. Navy and Military Sealift Command vessels, with deep expertise in CASREP-driven corrective maintenance, cyclical maintenance programs, and critical system remediation aboard naval auxiliaries. The contractor delivers precision shipyard services including propulsion system repairs, rescue boat engine overhauls, liferaft certification, and C4 system support, often conducted in-port at strategic Pacific locations such as Busan, South Korea. Their technical proficiency spans naval logistics, marine mechanical systems, and compliance with U.S. Navy maintenance directives, enabling rapid response to operational readiness requirements under austere conditions. The company maintains a consistent and trusted relationship with the Department of Defense, particularly supporting naval surface forces and MSC fleet assets. Their work focuses on sustaining the operational availability of critical logistics and support vessels through timely, mission-critical repairs that align with Navy maintenance cycles and CASREP protocols. This long-standing engagement reflects a proven ability to meet stringent military standards for quality, safety, and schedule adherence in forward-deployed environments. SUNJIN ENTECH’s primary industry focus is shipbuilding and repairing (NAICS 336611), with an exclusive specialization in military vessel sustainment rather than new construction. They operate at the intersection of naval engineering and expeditionary logistics, serving as a niche provider for complex, time-sensitive repairs on U.S. government-owned ships operating in the Indo-Pacific region. Their market positioning is defined by responsive, on-site technical execution rather than large-scale fabrication. The entity is structured as an 8H (foreign-owned small business) with headquarters in Busan, South Korea, and no federal certifications on record. Its geographic presence enables direct access to key U.S. naval operating areas, positioning it as a critical regional support partner for sustained maritime operations.
