Designated the HSS-2 (Helicopter, anti-Submarine, Sikorsky), this helicopter would enter service as the SH-3 Sea King. In 1957, Sikorsky engineers were working on a new model for the United States Navy to replace the H-34s, used for anti-submarine warfare. The fuselage layout was used by Sikorsky for the larger CH-53 variants, and by the much later (though similarly sized) S-92. It features a substantially revised fuselage with a rear loading ramp, a conventional, though watertight, hull instead of the S-61's boat-hull, and retractable tricycle landing gear.

Please consult our helpful Bluetooth Setup Guide. We suggest you install the app before purchasing the altimeter, to make sure your device is compatible. Integration with Facebook, Instagram, Twitter, and Flickr allow you to share your flights with just a tap.ĪltimeterThree includes a recharging cable, and can be recharged from any USB port. If GPS is enabled on your phone, the location of each flight is saved, and can be viewed on a map. You can view an interactive graph of altitude (and for certain sports, a climb/sink and/or 3-axis acceleration) and produce a Microsoft Excel™ spreadsheet of flight data for further analysis. It captures your notes and observations on each flight. It is small enough to go almost anywhere, and it can used for almost any flying activity. If you would like to collect and share flight data, then this is the altimeter for you. AltimeterThree is a flight altitude recorder that is controlled by your smartphone or tablet.
