It was accompanied by a NASA chase plane.<\/p>\n<p>The plane&#8217;s unique shape is designed to greatly reduce the explosive-like sonic boom normally produced when an aircraft breaks the sound barrier, lowering the volume to a muffled &#8220;sonic thump&#8221; no louder than slamming a car door.<\/p>\n<p>Perfection of such low-decibel flight technology is aimed at overcoming one of the primary obstacles to supersonic commercial flight, long restricted over populated areas on land due to noise concerns, according to Lockheed.<\/p>\n<p>Getting the plane off the drawing board and into the air was not inexpensive. NASA has paid Lockheed more than $518 million since 2018 to develop and demonstrate X-59, according to agency contracting data.<\/p>\n<p>The single-engine jet &#8211; measuring just under 100 feet (30 meters) from nose to tail &#8211; flew at subsonic speeds on its first flight, as expected, reaching 230 mph (370 kph), according to Lockheed Martin. Its peak altitude during the flight was 12,000 feet (3,660 meters).<\/p>\n<p>About 200 aerospace workers and their families watched the takeoff from a safe distance parked along a nearby highway.<\/p>\n<p>Item 1 of 5 On it\u2019s first flight, NASA&#8217;s experimental quiet supersonic aircraft X-59 takes off from runway 7 at Palmdale USAF Plant 42 in Palmdale, California, U.S. October 28, 2025.

But the plane was retired in 2003 due to high operating costs, limited seating and sluggish passenger numbers following a fatal crash in July 2000 and the September 11 attacks in 2001.<\/p>\n<p>In press materials posted online last month, NASA said the X-59&#8217;s first flight would be a \u201clower-altitude loop at about 240 mph (386 kph) to check system integration, kicking off a phase of flight testing focused on verifying the aircraft\u2019s airworthiness and safety.\u201d<\/p>\n<p>During subsequent test flights, the X-59 will travel higher and faster, eventually exceeding the speed of sound &#8211; approximately 761 mph (1,225 kph) at sea level.<\/p>\n<p>The California Manufacturers &amp; Technology Association earlier this month named the X-59 as 2025&#8217;s &#8220;Coolest Thing Made in California&#8221; in its annual statewide technology contest.<\/p>\n<p>&#8220;This work sustains America&#8217;s place as the leader in aviation and has the potential to change the way the public flies,&#8221; U.S. Transportation Secretary Sean Duffy, who is also acting NASA administrator, said in a statement.<\/p>\n<p data-testid=\"SignOff\" class=\"text-module__text__0GDob text-module__dark-grey__UFC18 text-module__regular__qJJtA text-module__extra_small__8Buss body-module__full_width__kCIGb body-module__extra_small_body__Bfz20 sign-off-module__text__LQAMP\">Reporting by David Swanson in Palmdale, California;
