North-American's oft-forgotten YF-93A (NA-157) was an advanced version of the F-86A Sabre day fighter designed for the penetration fighter reqirement. It was originally designated the F-86C and was designed around NACA flush inlets and a 8,000 lb thrust J48 afterburning engine with three times the fuel of the F-86A, which gave it extremely long range. The two other penetration fighter candidates (the XF-88 and XF-90) had flown much earlier than the YF-93. All three types were not developed beyond the prototypes as the penetration fighter requirement was dropped by the Air Force. The aircraft sported F-86-style w ings and tail mated to a new beffy fuselage with added electronics and 6-20mm cannon. The increased weight of the design led to a redesigned and strengthened dual-wheel main undercarrige. Only two-aircraft were built and the NACA flush intakes were replaced on ship one with conventional ram intakes resulting in increased overall performance. After retirement the two YF-93As were utilized at Moffett Field, CA, for further NACA testing before being scrapped.","brand":"Naval Fighters","offers":[{"title":"Default Title","offer_id":53788755231057,"sku":"NFAF227","price":21.85,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0865\/4992\/2129\/files\/NFAF227.jpg?v=1778880746","url":"https:\/\/www.jadlamracingmodels.com\/products\/valiant-wings-publishing-nfaf227-north-american-yf-93a","provider":"Jadlam Toys \u0026 Models","version":"1.0","type":"link"}
