Editor’s Note

The changing nature of warfare, rising conflicts and the never-ending great-power competition has given rise to complex geometries in global geopolitical positioning. The world's future is filled with eternal uncertainty. The advances in technology such as quantum computing. artificial intelligence and digital surveillance have transformed the military worldwide. As a driving force, technology has embedded itself in the power showbiz and has initiated an unprecedented competition between global powers including the emerging middle power. Acquiring innovative power, capacity to invent and adapting fast to new technologies is now a key determinant for all involved in the ongoing power game in the emerging new world order.

GE Marine’s LM500 to Power ROKN’s PKX-B Batch-II Patrol Boats

ROKN has begun the production of PKX-B Batch-II patrol boats, to include LM500 engines

EVENDALE, OH. The Republic of Korea’s Navy has selected GE Marine’s LM500 gas turbines to power the first four PKX-B Batch-II ships. Two LM500s, each rated at approximately 4.6 MW, will help propel one of the fastest and most technologically advanced vessels in the ROKN fleet with a top speed of 40 knots.
A total of 32 LM500 gas turbines are aboard 16 PKX-B Batch-I ships, which have all been delivered. Batch-II includes an additional 18 ships, with the first four officially contracted for construction in late 2022. The gas turbine hardware will be manufactured in GE’s Lynn, MA facility, and delivered to Hanwha Aerospace, a GE marine system partner, who will assemble and test the engines before delivering them to HJ Shipbuilding & Construction for installation.
“GE has supplied the ROK Navy with 155 marine gas turbines for 91 ships to date, and we are honored that GE marine gas turbines will continue to power their newest patrol boats. We look forward to further strengthening our relationships in-country for this next generation ship,” said Mark Musheno, Vice President, Sales and Marketing for GE Marine.
The LM500 is derived from GE’s TF34/CF34 turbofan aircraft engines and has 90% commonality with the CF34 engine that powers the popular CRJ100/200 regional jet with more than 14 million hours of operation. The simple cycle LM500 is a two-shaft gas turbine consisting of a gas generator, a free power turbine and cold-end drive capabilities. The 14-stage axial flow compressor offers a 14.5:1 pressure ratio.
The LM500 gas turbine engine is a perfect fit for the PKX-B patrol boats because it incorporates the latest in proven design technology and corrosion-resistant materials to provide a mature design with maximum reliability and component life.
GE ensures that its gas turbines meet the ever-changing needs of its customers, either by making advances to existing equipment or by introducing new technologies to improve overall performance. Each of GE’s six aeroderivative marine gas turbines are compact, lightweight and produce low emissions: LM500 (4.6 MW), LM2500 (25.1 MW), LM2500+ (30.2 MW), LM2500+G4 (35.3 MW), LM6000PC (46.1 MW) and LM6000 (52.7 MW).
GE Marine’s gas turbine business is part of GE Aerospace, headquartered in Cincinnati, Ohio. GE is one of the world’s leading manufacturers of marine propulsion products, systems, and solutions, including aeroderivative gas turbines ranging from 6,100 to 70,656 shaft horsepower/4.6 to 52.7 megawatts.
