Boeing developed it and its design was based on that of the Boeing 707. With a distinctive and easily identifiable radar dome, the aircraft is capable of offering all-weather surveillance, command, control, and communication capabilities. Get all the latest aviation news from Simple Flying! The plane is currently in service with the United States Air Force, the French Air and Space Force, the Royal Saudi Air Force, and the Chilean Air Force, and a total of 68 aircraft rolled out of Boeing factories during a 15-year production run from 1977 to 1992. The E-3 Sentry was originally designed to replace the Lockheed EC-121 Warning Star, an earlier AWACS platform that was still powered by piston engines. After a competitive development process, Boeing was chosen by the Air Force for the project, and its prototype was fitted with radar systems designed by Westinghouse and Hughes. The former, a pulse-Doppler radar , was ultimately selected for testing and eventual application. The first production E-3 entered service with the United States Air Force in 1977, and deliveries continued throughout the next ten years. Over the years, E-3 Sentry aircraft were delivered as follows: Customer: Number of E-3 Sentry aircraft purchased: United States Air Force 34 North Atlantic Treaty Organization (NATO) 18 Royal Air Force 7 Royal Saudi Air Force 5 French Air and Space Force 4 A capable aircraft that has served an important role over time Throughout the years, the E-3 Sentry has been upgraded multiple times for it to remain capable and relevant in the world of modern aerial combat. Northrop Grumman would eventually be given the task of managing the aircraft's control systems. The E-3 Sentry would ultimately be the last aircraft produced based on the Boeing 707, and it is set to be retired by 2027, which will mark the end of the aircraft family's extensive operational history . While fighter jets and stealth bombers often get the majority of attention, the importance of the operational role played by airborne early warning and control aircraft is difficult to fully quantify. These aircraft are critical elements of the Air Force's inventory and provide crucial support and intelligence-gathering capabilities that support any military initiative. Unlike JSTARS, AWACS is showing no signs of being ready for retirement. As a result, the E-3 Sentry has been a crucial piece of the Air Force's operational capabilities since it first entered service. Let's take a deeper look at the development, operational history, and specifications of the Boeing E-3 Sentry. The aircraft's development process began in 1963 The E-3 Sentry was designed to leverage advancements in radar technology with computer-managed real-time data capabilities, which would allow it to detect low-flying aircraft and distinguish enemy targets from radar clutter. The aircraft's development began in the early 1960s, and Boeing's 707 was eventually chosen to be the platform for the new radar technologies that the Air Force was developing. The earliest prototypes, which were designated as EC-137Ds, first took to the skies in 1972, and would later be equipped with the Westinghouse radar that the Air Force had approved. This radar offers next-generation digital processing capabilities and Doppler frequency resolution. Mission systems for the aircraft would be designed by IBM and Hazeltine, and the first production variant took to the skies in 1975 for the first time and would later be delivered in 1977. The E-8 Joint STARS tracks targets on the ground with high accuracy while the E-3 Sentry flies high above, watching everything in the skies. Additional elements of the aircraft's systems have been reproduced for other aircraft Over time, the Boeing 707 would go out of production, but NATO allies would remain interested in the E-3 Sentry's capabilities. As a result, Japan operates modified 767 aircraft equipped with E-3 Sentry systems. The Air Force has also already begun to retire its E-3 Sentry fleet. According to the organization , the first E-3 Sentry aircraft retirement took place back in March 2023, demonstrating the beginning of a transition towards newer AWACS platforms. In the United States and the United Kingdom, the E-3 Sentry is set to be replaced by the E-7 Wedgetail, an AWACS platform derived from the Boeing 737, according to Airforce Technology . Here are some specifications for the E-3 Sentry: Category: E-3 Sentry Specification: Maximum takeoff weight (MTOW): 347,000 pounds Range: 4,000 miles Service ceiling: 29,000 feet The E-3 Sentry has an extensive operational history The E-3 Sentry has played a critical role in airborne surveillance and control missions since it first entered service in the late 1970s . The United States Air Force's E-3 Sentry fleet is primarily based out of Tinker Air Force Base in Oklahoma, with some additional units based in the Pacific. The aircraft has proven its worth over the years, first entering combat during Operation Desert Storm, where it flew nearly 400 missions and assisted in 38 of 41 air-to-air kills made during the conflict. The aircraft also played a critical role in the 1999 bombing of Yugoslavia and Operation Inherent Resolve against the Islamic State in 2015. The Royal Air Force used the aircraft extensively to assist in airstrikes against the Islamic State until the aircraft was retired in 2021. The French Air and Space Force is currently evaluating potential successors to its fleet. In addition, NATO used its fleet extensively during Operation Eagle Assist in the years following the September 11th terrorist attacks and during the conflict in Afghanistan .Australia dumps plan for fines for social media giants enabling misinformation
The deal, announced on Tuesday night, will see hostilities between Israel and Iran-backed militants Hezbollah suspended for 60 days, with both sides withdrawing from southern Lebanon. Brokered by the US and France, the agreement is designed to provide a permanent end to the conflict, US President Joe Biden said following the announcement. But Israeli ministers insisted it would resume strikes on Lebanon if Hezbollah breached the terms of the ceasefire, while the deal does not affect Israel’s continuing war with Hamas in Gaza. In a statement, Sir Keir Starmer described the deal as “long overdue”, saying it would “provide some measure of relief to the civilian populations of Lebanon and northern Israel, who have suffered unimaginable consequences during the last few months of devastating conflict and bloodshed”. He said: “Now, this deal must be turned into a lasting political solution in Lebanon, based on Security Council Resolution 1701, that will allow civilians to return permanently to their homes and for communities on both sides of the border to rebuild. “The UK and its allies will continue to be at the forefront of efforts to break the ongoing cycle of violence in pursuit of a long-term, sustainable peace in the Middle East. “We must see immediate progress towards a ceasefire deal in Gaza, the release of all hostages and the removal of restrictions on desperately needed humanitarian aid.” The announcement of the deal follows a day of intense Israeli air strikes in Beirut, with local authorities saying at least 24 people were killed in the bombardment while Hezbollah continued to fire rockets into northern Israel. Recommending the ceasefire to his cabinet, Israeli Prime Minister Benjamin Netanyahu said the deal would isolate Hamas in Gaza and allow Israel to focus more on Iran, which supports both Hamas and Hezbollah and has staged attacks on Israel in recent months. Foreign Secretary David Lammy said the announcement offered “hope” and must become “a turning point that builds momentum towards a lasting peace across the Middle East”. He said: “The UK was the first G7 country to call for an immediate ceasefire between Israel and Lebanese Hezbollah in September and we have worked relentlessly since with our allies and partners to apply pressure to end this conflict since. “We strongly urge all parties to use this agreement to open a pathway to a lasting peace.” While aid organisations have welcomed the ceasefire, they have also called for it to be made permanent and extended to the conflict in Gaza. Amelia Whitworth, head of policy, campaigns and youth at the children’s charity Plan International UK, welcomed news of the deal. She said: “It is essential that all parties respect this ceasefire so that vital humanitarian aid can be delivered to the children and families that desperately need it.” Ms Whitworth added: “Today’s agreement must act as a vital step towards a sustained, permanent ceasefire – both in Lebanon and across Gaza and the wider Middle East region. “The horror must stop immediately, all children deserve to enjoy their childhood free from the threat of violence.” Paras Tamang, global humanitarian director at ActionAid, echoed her comments, saying the ceasefire would provide “temporary relief” for civilians but was “not an acceptable long-term solution to the crisis”. Mr Tamang said: “Whilst air strikes may stop for a while, the fallout from these attacks will continue to be felt for years to come. “More humanitarian aid is needed to help the hundreds of thousands of people who have lost everything.” According to the UN, more than 3,700 people, including 240 children, have been killed in Lebanon since the latest round of fighting began in October 2023, while around 900,000 have been displaced.
