The General Electric LM1500 is an industrial and marine gas turbine produced by GE Aviation.
The LM1500 is a derivative of the General Electric J79 aircraft engine series.
[3] Its first application was for the first US sea-going research hydrofoil, HS Denison.
[1] Conversion as a marinised turboshaft engine involved two major changes: the addition of a free power turbine, and corrosion-protection by the addition of internal coatings and a maintenance scheme of freshwater rinsing to prevent salt damage.
[4] Over time, its commercial applications widened to include marine propulsion[5] and its use at oil and gas pipeline compressor stations.
