World's most secretive jet spotted over Area 51
The US Air Force's top-secret RAT55 jet was spotted soaring over Area 51 in Nevada, confirming rumors that this enigmatic radar plane operates from the clandestine Groom Lake facility. Aviation enthusiast Michael Rokita captured the aircraft from a vantage point 26 miles away near Tikaboo Peak, documenting its touch-and-go maneuvers and final landing on runway 32. Minutes after landing, the RAT55 was linked to Hangar 18, Area 51's largest and most mysterious hangar, as its massive sliding doors were seen open, suggesting the jet had taxied inside. The RAT55, distinguished by its 'fat nose,' 'hump on the top,' 'hump on the belly,' and 'big protrusion in the back,' is a specialized aircraft designed for in-flight radar cross-section testing. This capability allows it to evaluate the stealth profiles of other aircraft mid-air, a critical function rumored to have supported the development of the RQ-80 unmanned aerial vehicle (UAV). Its operations are typically cloaked in secrecy, conducted in restricted airspace like the R-258 range near Edwards Air Force Base, where it often vanishes from flight tracking by switching off its transponder. Rokita's sighting confirmed that RAT 55 uses the call sign 'Saber 98,' a thrilling breakthrough that ties the jet's covert communications to Area 51's operations, cementing its residence in Hangar 18. Using a Nikon P1000 camera and a custom binocular-smartphone setup, Rokita overcame technical challenges, including a dying battery and desert heat haze, to deliver this unprecedented evidence. Outfitted with advanced radar systems, RAT55 is believed to operate primarily as a test platform for evaluating the radar signatures of stealth aircraft. This includes both existing models, like the B-2 Spirit, which undergoes regular testing to ensure its radar cross-section meets expectations, and new prototypes. With at least two major manned stealth programs currently under development, the Northrop Grumman B-21 Raider and the Boeing F-47, RAT55's specialized capabilities are likely in high demand. RAT55, short for Radar Airborne Testbed, with '55' taken from its tail number, rarely leaves the skies over the sprawling, isolated test ranges of South-Central California and Southern Nevada, where it quietly carries out its secretive missions. The jet's taxiing to Hangar 18 is particularly tantalizing due to its conspiracy lore as the name's association with alien encounters, secret projects and black-budget aircraft instantly sparks curiosity. Hangar 18 remained the largest hangar on the base until the mid-2000s, following its construction in the 1980s. Its towering height and massive doors could accommodate virtually any aircraft in the US inventory, making it ideal for testing, storage or perhaps even simultaneous classified projects. Some enthusiasts have speculated that the hangar may house a 'museum' of retired or experimental aircraft, hidden from public view. It was also last spotted in May, flying alongside a B-2 Spirit over Death Valley The combination of the legendary Hangar 18 name and its location at Area 51 has cemented its almost mythical status, feeding decades of rumors that have fueled conspiracy theories, from alien technology to top-secret aerospace programs. RAT55's recent appearance there only adds fuel to the speculation, suggesting that whatever goes on inside may be as secretive and extraordinary as the legends imply. It was also last spotted in May, flying alongside a B-2 Spirit over Death Valley. Photographer Julian Elnasser described his RAT55 sighting to The Aviationist: 'I was staying in Las Vegas and saw it was out flying from Groom towards the R-2508. 'So I decided to try my luck and hurry on out to Death Valley near Furnace Creek. Approaching the town, I saw the two and immediately pulled over; they were pretty low. 'After the first pass, I moved closer to the valley itself and observed two more passes before they [returned to base].'

The US Navy is spending millions on testing new drone technology. Setbacks have been significant
The U.S. Navy has experienced several major setbacks in its efforts to develop a new fleet of drones in a race with China. Last month, the Navy was testing autonomous drone boats off the California coast when one vessel stalled. As officials worked to fix a software problem, another vessel plowed into the stalled boat, flipped over the deck, and crashed back into the sea, according to Reuters. The two vessels were built by American defense tech companies, Saronic and BlackSea Technologies. During a test conducted by the Navy weeks earlier, a support boat captain was flung into the water when another autonomous BlackSea vessel that it was towing unexpectedly sped up. This caused the support boat to capsize, four people familiar with the incident told the news agency. The captain declined to seek medical attention. The incident was initially reported by Defense Scoop. Both setbacks were due to software issues and human error. This included breakdowns in communication between onboard systems and external autonomous software, a person with direct knowledge of the issue told Reuters. Maritime drones have made a massive impact in the war between Russia and Ukraine, and U.S. military leaders have taken note. They have said repeatedly that they need a large number of aerial and maritime drones to stop a possible attack on Taiwan by China. Taiwan has begun building up its own naval drone fleet. The drones developed in Ukraine often look like speedboats with no seats and can carry weapons, explosives, and surveillance equipment. Primarily remote-controlled and costing nearly $250,000, they have been used for kamikaze missions to take down Russia's Black Sea Fleet. The U.S. is working to build an autonomous naval fleet that can move in swarms without being controlled by humans, costing as much as several million dollars per vessel. Hudson Institute autonomous warfare expert Bryan Clark told Reuters that the recent test mishaps reveal the challenges that the Navy is facing and that it will have to adapt 'its tactics as it better understands what the systems can do and what they can't do." A top admiral of the Navy's autonomous maritime drone acquisition unit was fired in late May. A senior Pentagon official shared their concerns regarding the program during a meeting with Navy leaders last month, according to the news agency. Following the California crash, the Pentagon's Defense Innovation Unit has put a contract with L3Harris, valued at nearly $20 million, on hold. L3Harris is one of the companies providing the software used to control some of the vessels. A spokesperson for the Pentagon told Reuters that they have conducted the drone tests as part of a "competitive and iterative approach, between operators and industry." In 2023, the Pentagon started its $1 billion Replicator program, a plan to acquire thousands of aerial and maritime drones, as well as the software to control them. The initial systems stemming from the program are set to be announced this month. Procurement records show that the Navy has committed at least $160 million to BlackSea, which manufactures dozens of Global Autonomous Reconnaissance Craft boats each month. Saronic manufactures the sea drone Corsair, but it hasn't yet revealed a major contract. According to federal procurement records, the company has generated at least $20 million stemming from prototype agreements. Jim Kilby, the acting chief of naval operations, visited a BlackSea facility in June. "These systems will play a critical role in the future of naval warfare by extending fleet reach, improving situational awareness, and increasing combat effectiveness," he said at the time, according to Reuters. Autonomous weapons expert T.X. Hammes told the news agency that the Navy is attempting to change decades of tradition quickly. "You've got a system that's used to building big things, taking years to make a decision, and now suddenly you're asking them to move fast," he said. Last month, President Donald Trump's signature domestic policy package, known as the 'Big, Beautiful Bill', was passed into law. It includes nearly $5 billion for maritime autonomous systems. However, the Navy has faced skepticism from the Trump administration. The Navy's drone procurement unit, called the Program Executive Office Unmanned and Small Combatants, was recently placed under review, four people familiar with the situation told the news agency. It may be restructured or shut down. A spokesperson for the Navy, Timothy Hawkins, told Reuters that the unit stands by its mission.

Tech selloff pushes down Nasdaq, S&P 500; investors cautious ahead of Fed meeting
Aug 20 (Reuters) - Wall Street's main indexes fell on Wednesday, with a selloff in tech stocks driving the Nasdaq to a two-week low as caution prevailed ahead of the Federal Reserve's highly anticipated Jackson Hole symposium this week. After driving much of the market's recovery from the April selloff, tech stocks are pulling back as investors reassess high valuations. The S&P 500 technology index (.SPLRCT), opens new tab slid 1.1% on the day. "We're seeing more downside in the names that have run the most over the last four months, in tech in particular, and maybe a little bit of profit taking in anticipation of more data on the economy and more guidance from the Fed," said Jim Baird, chief investment officer at Plante Moran. Analysts listing other factors behind the tech sell-off mentioned OpenAI CEO Sam Altman's comments last week about artificial intelligence stocks being "in a bubble," and a Massachusetts Institute of Technology study that showed many tech companies were struggling to translate AI into actual profits. Some investors also worried about government interference in the private sector. President Donald Trump's administration is looking into taking equity stakes in chip firms such as Intel (INTC.O), opens new tab, weeks after unprecedented revenue-sharing deals with Nvidia and AMD. Nvidia (NVDA.O), opens new tab slid 1.2% and Advanced Micro Devices (AMD.O), opens new tab fell 2%, while Intel (INTC.O), opens new tab and Micron (MU.O), opens new tab fell between 7% and 5.3%. Nvidia's quarterly results on August 27 are keenly awaited for clues on demand for artificial intelligence. Other megacap growth names such as Apple and Meta (META.O), opens new tab also came under pressure, falling 1.8% and 0.9%, respectively. "It's much more about profit-taking and temporary rebalance here," said Phil Blancato, chief executive officer of Ladenburg Thalmann Asset Management in New York. "If you get a Federal Reserve (interest rate) cut or a mention of it on Friday, this will reverse pretty quickly, but this is a lot to do with names pushed up to really lofty levels." At 1:55 p.m. the Dow Jones Industrial Average (.DJI), opens new tab rose 9.10 points, or 0.02%, to 44,931.37, the S&P 500 (.SPX), opens new tab lost 23.18 points, or 0.36%, to 6,388.19 and the Nasdaq Composite (.IXIC), opens new tab lost 182.28 points, or 0.85%, to 21,132.67. The Nasdaq was on track for its biggest two-day drop since April, when U.S. tariff announcements had rattled global financial markets. Minutes from the Fed's July meeting, where interest rates were left unchanged, showed almost all policymakers viewed it as appropriate to maintain the target range for the federal funds rate at 4.25% to 4.50%, despite two dissenters. Remarks from Atlanta Fed President Raphael Bostic are expected on Wednesday afternoon. The central bank's annual conference in Jackson Hole, Wyoming, kicks off on Friday, with Chair Jerome Powell expected to speak, remarks that will be closely watched for policy signals. Investors have been pricing in a 25-basis-point rate cut in September, according to data compiled by LSEG. Meanwhile, investors also monitored Trump's call for the resignation of Fed Governor Lisa Cook, with the president citing allegations that she was involved in mortgage fraud. Earnings from big retailers, seen as a barometer for the health of the American consumer, are also due this week as sentiment has taken a hit from concerns that tariffs could drive prices higher. Target (TGT.N), opens new tab tumbled 6.6% after the company named a new CEO and retained its annual forecasts that were lowered in May. Cosmetics giant Estee Lauder (EL.N), opens new tab fell 5.3% after tariff-related headwinds weighed on its annual profit forecast. Declining issues outnumbered advancers by a 1.06-to-1 ratio on the NYSE. There were 125 new highs and 55 new lows on the NYSE. The S&P 500 posted 21 new 52-week highs and no new lows while the Nasdaq Composite recorded 31 new highs and 110 new lows.
