At Northrop Grumman Sperry Marine we are proud of our reputation for making great products. A testament to that reputation is the number of products that continue to work, often long after model discontinuation. Our job is to provide the service and parts necessary to maintain equipment operation and performance.

Support policy of ten years
Northrop Grumman Sperry Marine long-standing support policy of manufacturing and providing replacement parts and support for equipment for ten years after model discontinuation allows you to keep these products active for many years, thereby enhancing return on investment. That policy remains in place. However, many Northrop Grumman Sperry Marine products around the world and others remain in use, beyond the ten year support window.

While Northrop Grumman Sperry Marine generally maintains a working inventory of replacement parts for on-going service and preventive maintenance beyond the ten-year support window, maintaining this inventory isn't always possible. In cases where required parts and/or service are no longer available, we suggest to contact us or local representative for assistance.
