than the <a href="/wiki/Bell_47" title="Bell 47">Model 47</a>, which utilized a scaled-up version of the Model 47's rotor system. Three prototypes were built, but serious rotor problems and complexity of mechanical systems precluded production. The initial Model 42 variant was civilian, but the <a href="/wiki/United_States_Air_Force" title="United States Air Force">United States Air Force</a> ordered the development of its military variant, the <b>Model 48</b>. Two prototypes were ordered as the <b>XR-12</b>, powered by a single 540 hp (403 kW) <a href="/wiki/Pratt_%26_Whitney_R-1340-AN-1" class="mw-redirect" title="Pratt & Whitney R-1340-AN-1">Pratt & Whitney R-1340-AN-1</a> <a href="/wiki/Radial_engine" title="Radial engine">radial engine</a> and featuring seating for five. Of very similar construction to the Model 42, the Model 48 had a shorter rotor mast. A production batch of 34 helicopters was ordered, under the designation R-12A, but cancelled in 1947.<sup id="cite_ref-Pelletier_1-1" class="reference"><a href="#cite_note-Pelletier-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>Another enlarged prototype (the XR-12B, Model 48A) with seats for eight plus two pilots and a more powerful 600 hp (447 kW) Pratt & Whitney R-1340-55 engine was also ordered, followed by ten pre-series YR-12B helicopters, with a glazed nose, instead of the car-like nose of the Model 42 and XR-12. While under flight test the helicopter was redesignated the <b>H-12</b>, but the results were not satisfactory, as there were major problems with the main rotor due to blade weaving and poor rotor governor performance.<sup id="cite_ref-Pelletier_1-2" class="reference"><a href="#cite_note-Pelletier-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Operational_history">Operational history</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Bell_H-12&action=edit&section=2" title="Edit section: Operational history"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:NNSA-NSO-913.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/c/c6/NNSA-NSO-913.jpg/220px-NNSA-NSO-913.jpg" decoding="async" width="220" height="176" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/c6/NNSA-NSO-913.jpg/330px-NNSA-NSO-913.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/c6/NNSA-NSO-913.jpg/440px-NNSA-NSO-913.jpg 2x" data-file-width="800" data-file-height="639" /></a><figcaption>Journalists and news reported examine a Model 12, which was used to survey the area after a nuclear test in Nevada.
