The United States Air Force is upgrading its long-range strike power with the induction of the B-21 Raider , its next-generation stealth bomber . This marks a significant shift in U.S. air power as the B-21 joins legacy bombers like the B-2 Spirit B-1B Lancer , and B-52H Stratofortress , each of which remains active in global operations. Together, these aircraft form the backbone of U.S. strategic deterrence and long-range combat capabilities.The B-21 Raider is the newest addition to America's bomber fleet, developed by Northrop Grumman under the Long Range Strike Bomber (LRS-B) program. Its design aims to replace the older B-2 and B-52 bombers. The aircraft had its first flight in late 2023, and operational deployment is expected later this decade.The U.S. Air Force plans to procure at least 100 B-21 bombers, with the possibility of increasing the number to 200. The B-21 is designed to operate in contested environments, carry both nuclear and conventional weapons, and remain effective against evolving threats through its digital and open-systems design.Crew: 2Wingspan: 132 ftMax speed: Mach 0.8+Ceiling: 50,000 ftPayload: 20,000 lb in weapons bayArmament includes AGM-181 LRSO missiles and JDAM bombsThe B-2 Spirit remains a critical part of the U.S. Air Force's ability to strike distant, high-value targets. Developed by Northrop Grumman and partners, it uses stealth technology and a flying wing design to avoid radar detection. Its long range and ability to deliver nuclear or conventional weapons make it central to U.S. deterrence.In Operation Midnight Hammer, B-2s flew a 37-hour mission from Whiteman Air Force Base to Iran, striking nuclear targets using GBU-57 bunker-buster bombs.Crew: 2Wingspan: 172 ftMax takeoff weight: 336,500 lbPayload: 40,000 lbCeiling: 50,000 ftRange: IntercontinentalUnit cost: $1.157 billion (FY98 dollars)Inventory: 20 aircraft (1 test unit)The B-1B Lancer remains a key asset for delivering the largest conventional payload in the U.S. Air Force. Built by Boeing, the aircraft features variable-sweep wings and is powered by four afterburning turbofan engines. It is capable of low-level penetration at high subsonic speeds.Upgrades to its radar, communications, and digital systems have kept the B-1B relevant for modern missions. It carries a mix of guided and unguided munitions, and its survivability is enhanced by electronic jamming systems, radar decoys, and countermeasure flares.Originally built for nuclear missions, the B-1B was converted to a conventional-only role by 2011.Crew: 4Wingspan: 137 ft (extended)Max speed: Mach 1.2Ceiling: 30,000+ ftPayload: 75,000 lbUnit cost: $317 millionInventory: 62 active, 2 test aircraftThe B-52H Stratofortress continues to serve in the U.S. Air Force more than 70 years after its first flight. Known for its durability and global range, the B-52 can deliver both nuclear and conventional weapons. It has participated in operations from Desert Storm to the fight against ISIS.Modern B-52s are fitted with advanced targeting pods and sensors, along with upgraded avionics and communication systems. Its long-range and large payload capacity allow it to conduct a wide range of missions, including maritime strike and air interdiction.The B-52H is expected to remain in service beyond 2050.Crew: 5Wingspan: 185 ftMax speed: Mach 0.84Ceiling: 50,000 ftPayload: 70,000 lbRange: 8,800 milesUnit cost: $84 millionInventory: 58 active, 4 test, 18 reserveThe U.S. Air Force maintains these four bombers to ensure a flexible, survivable, and long-range strike capability. While legacy aircraft continue to undergo upgrades to remain mission-ready, the B-21 Raider signals a generational shift in American air power.As stated by the U.S. Air Force, these bombers ensure 'America's ability to conduct precise, sustained, and survivable global strike operations now and into the future.'

Karnataka generates 200MW solar power under Kusum-C; 545MW to follow
Under the Kusum-C scheme, which aims to solarise agricultural feeders and provide daytime electricity supply to farmers' pumpsets, 200MW of electricity is being produced. In the coming months, 545MW of electricity will be generated, stated energy minister KJ George. Speaking to reporters after the energy department's progress review meeting of Hassan district, held on Friday at the Zilla Panchayat hall in the city, George said, "Under the Kusum-C scheme, construction of solar units with a capacity of around 200MW is completed. In the next few months, solar units with a capacity of 545MW will be commissioned at 93 locations. This will help provide an adequate daytime electricity supply to farmers." "The state govt has set a target of generating 2,400MW of solar electricity through feeder solarisation of agricultural pumpsets under the Kusum-C scheme. Recently, chief minister Siddaramaiah inaugurated a solar power unit established under the Kusum-C scheme in Gauribidanur. The feeder solarisation work is progressing at a rapid pace," the energy minister added. Under the Kusum-C scheme, generating 1MW of electricity requires 4 acres of land. If govt land is available, CM Siddaramaiah has directed that it be allocated free of cost. However, private power producers must pay ₹25,000 per acre, which will be deposited with the district commissioner and used to improve govt schools and anganwadis in villages where the substations are located, the minister elaborated. "If private land is used, developers awarded the power generation contracts will lease the land and pay landowners a minimum of ₹25,000 per acre," George said. Of the 4 lakh unauthorised irrigation pumpsets in the state, 3 lakh are already regularised. For pumpsets within 500m of power feeders, transformers will be installed by the department. Those beyond 500m will receive solar pumpsets under the Kusum-B scheme, he said. Earlier, during a progress review meeting, the district MLAs raised issues concerning the energy department in their constituencies. In response, George instructed the CESC MD to take swift action and reiterated that officials should proactively consult elected representatives and follow through on their suggestions. MP Shreyas Patel , MLA and Housing Board chairman KM Shivalingegowda, MLAs K Manju, Swaroop Prakash, CN Balakrishna, HK Suresh, and S Manjunath were present.

B2 bombers roars over White House; Donald Trump and Melania Trump celebrate U.S. Independence Day
U.S. President Donald Trump signed his flagship tax and spending Bill into law on Friday (July 4,2025), capping a grandiose White House Independence Day ceremony featuring a stealth bomber fly-by. Mr. Trump also played down criticism by Democrats that the unpopular legislation will slash social welfare programs, saying: 'You won't even notice it.' With First Lady Melania Trump at his side, Mr. Trump watched from the White House balcony as two B-2 bombers — the same type that recently struck Iranian nuclear sites — roared overhead, accompanied by F-35 and F-22 fighter jets. The 79-year-old's victory lap came a day after Republicans fell into line and passed the sprawling mega-Bill, allowing him to sign it as he had hoped on the Fourth of July holiday. The Bill honours many of Mr. Trump's campaign promises: extending tax cuts from his first term, boosting military spending and providing massive new funding for Mr. Trump's migrant deportation drive. 'Never been anything like it' The legislation's signing caps two weeks of significant wins for Mr. Trump that have seen him tighten his grip on power and his party alike. The successes include the recent Iran-Israel ceasefire that was sealed after what he called the 'flawless' U.S. air strikes on Iran. Pilots who carried out the bombing on Iran were among those invited to the White House event, which included a picnic for military families on the South Lawn. 'The last two weeks, there has never been anything like it, as far as winning,' said Mr. Trump. Mr. Trump had however forced through the tax Bill despite deep misgivings in the Republican Party that it would balloon the national debt. The legislation is expected to pile an extra $3.4 trillion over a decade onto the U.S. deficit. It squeezed past a final vote in the House of Representatives 218-214 after Republican Speaker Mike Johnson worked through the night to corral the final group of dissenters. Mr. Trump thanked Johnson at the White House event, saying: 'What a job.' 'Horrible day' Mr. Trump's billionaire former ally Elon Musk was among the most vocal critics, and he has pledged to set up a new political party to oppose Republicans who backed the Bill. Democrats and many voters have meanwhile expressed concerns that the 'big beautiful Bill' will gut health and welfare support. The Bill will force through the largest cuts to the Medicaid health insurance program for low-income Americans since its 1960s launch, while also shrinking federal food assistance programs. Up to 17 million people could lose their insurance coverage under the Bill, according to some estimates. Scores of rural hospitals are expected to close as a result. But Mr. Trump played down the concerns. 'They've developed a standard line, and we can't let them get away with it. 'Oh, it's dangerous. Oh, everybody's going to die.' It's actually just the opposite,' said Mr. Trump. Democrats hope public opposition to the Bill will help them flip the House in the 2026 midterm election, pointing to data showing that it represents a huge redistribution of wealth from the poorest Americans to the richest. People attending the Fourth of July parade in Washington on Saturday had mixed feelings. 'Yesterday was a horrible day, today is the best part of America,' said Elisabeth Hubir, 70.
