The technological milestone can reach speeds of Mach 3.5 and soars to an altitude of 65,000 feet.
This makes it impervious to countermeasures and GPS jamming systems.
It uses a ramjet engine, enabling supersonic speeds and a range of up to 150km.
The missile is equipped with AI technology, GPS, and a sensor system that corrects errors in real-time.
An important feature is that the Sceptre TrBM 155HG can be powered by diesel, JP-4, or JP-8 fuel.
Unlike typical solid-fuel missiles, the supersonic shell's fueling design boosts shelf life to over 20 years and cuts storage risks.
The Sceptre's propulsion system also reduces reliance on niche energetics, letting the defence firm source fuel from established logistics networks and strengthening the supply chain.
Chad Steelberg, CEO and founder of Tiberius Aerospace, described the state-of-the-art missile as a "10X solution" in range precision, cost-effectiveness, survivability and operational adaptability.
He added: "This is a weapon designed for the future battlefield: fast, precise, and resilient in a denied environment."
It comes after Britain hit a major milestone in the race for hypersonic supremacy – with a powerful new missile engine tested 233 times and hailed as a game changer for UK defence.
Putin develops yet another secret new hypersonic missile - this time mini-sized - in bid to outdo West, as 6,100 mph Zircon to be tested next month
The new air-breathing propulsion system, designed to fire cruise missiles at speeds of over five times the speed of sound, is part of a £1billion push to build a British hypersonic weapon by 2030.
The breakthrough comes as military experts warn a British version of Israel's famed Iron Dome missile shield would be "too prohibitively expensive" to protect the entire UK – leaving cities exposed to attacks from Putin's rockets.
Defence Secretary John Healey said: 'We are living in a more dangerous world and it has never been more important for us to innovate and stay ahead of our adversaries, equipping our forces with the technologies of the future.
'This milestone moment on hypersonics research, supported by British scientists and British small businesses, demonstrates another crucial area where we are working in lockstep with the United States to bolster our Armed Forces and strengthen our deterrence.'
The engine, developed through a joint effort between the Defence Science and Technology Laboratory (Dstl), the US Air Force Research Laboratory, and UK industry players like Gas Dynamics Ltd, was successfully trialled at NASA's Langley Research Centre in Virginia.
Over six weeks, scientists carried out 233 static tests across a range of supersonic and hypersonic speeds, analysing real-time data to tweak designs and boost performance.
Paul Hollinshead, Chief Executive of Dstl, said: 'This milestone represents a critical advancement in the UK's defence capabilities and reinforces our standing in the AUKUS hypersonic weapon development collaboration.
"The success of these tests highlights the UK's commitment to technological leadership and innovation in this crucial area.'
What is the Iron Dome – and is it really effective?
ISRAEL'S Iron Dome is a high-tech, all-weather mobile air defence system designed to intercept and destroy short-range threats like rockets, missiles, mortars and drones.
The system is made up of at least 10 batteries placed strategically around the country.
Each battery includes a radar detection system, a control centre to assess threats, and truck-towed launchers that fire radar-guided Tamir interceptor missiles.
How does it work?
The radar detects incoming projectiles and sends data to a central command that decides if the threat will hit a populated or strategic area. If it will, the system fires interceptors to destroy it mid-air – ignoring rockets headed for open spaces.
Range & reach:
The Iron Dome can take out targets launched from up to 43 miles away. Each launcher holds up to 20 interceptors, and the batteries together can protect nearly 60 square miles of land. Israel has worked on increasing the range to up to 155 miles and enabling the system to handle multiple threats from different directions.
How effective is it?
Very. Iron Dome has a reported success rate of around 90 per cent, according to its developer Rafael Advanced Defence Systems. It has intercepted thousands of rockets since its first combat use in 2011. During the 2021 conflict with Gaza, it stopped roughly 90 per cent of over 4,000 rockets fired into populated areas. In the October 2024 Iranian missile barrage, the system again proved its mettle, downing most of the 180 missiles fired.
Limits under pressure:
The system isn't invincible. On October 7, 2023, when Hamas fired thousands of rockets at once, it overwhelmed the system. Experts say there's a limit to how many incoming projectiles the Iron Dome can handle at once – and anything above that threshold can get through.
Part of a trio:
The Iron Dome is just one part of Israel's multi-layered defence network, alongside David's Sling (for medium-range missiles) and Arrow 2/3 (for long-range ballistic missiles), creating overlapping protection against a variety of aerial threats.
Bottom line:
Iron Dome is a battlefield game changer – incredibly effective against limited rocket fire, but not a silver bullet against massed missile barrages.

UK to build up to 12 new nuclear-powered attack submarines in major defence shake-up
The UK will build up to 12 new nuclear-powered attack submarines and invest £15 billion in its warhead programme. The UK is poised to construct up to 12 new nuclear-powered attack submarines and will pour £15 billion into its warhead programme, with the Prime Minister set to disclose these plans on Monday during the Government's strategic defence review. Major investments are queued for the UK's nuclear warhead programme this parliamentary session, along with commitments to maintain the current arsenal, as supported by 62 recommendations the Government aims to fully implement. However, there's been a debate over defence spending promises, after the Defence Secretary was unable to verify if the Treasury had secured budgeting to increase it to 3% of GDP by 2034. Part of the Aukus deal with the US and Australia, the creation of these submarines is projected to sustain 30,000 highly skilled jobs into the 2030s, along with generating 30,000 apprenticeships and 14,000 graduate positions over the forthcoming decade, according to the Ministry of Defence. Defence Secretary John Healey remarked: "Our outstanding submariners patrol 24/7 to keep us and our allies safe, but we know that threats are increasing and we must act decisively to face down Russian aggression. "With new state-of-the-art submarines patrolling international waters and our own nuclear warhead programme on British shores, we are making Britain secure at home and strong abroad, while delivering on our Plan for Change with 30,000 highly skilled jobs across the country." The £15 billion investment into the warhead programme will bolster the Government's pledges to sustain the continuous-at-sea nuclear deterrent, construct a new line of Dreadnought submarines, and facilitate all forthcoming enhancements. From the late 2030s, the array of up to 12 SSN-Aukus class attack submarines – conventionally armed yet nuclear-powered – are set to succeed the seven astute class submarines that the UK anticipates commissioning. The Government, in echoing the findings of the strategic defence review, has pledged to:. - Prepare the armed forces for readiness to engage in conflict should the need arise. - Enhance armament reserves and maintain scalability in production capacities to respond promptly in times of crisis or warfare. - Procure up to 7,000 domestically produced long-range missiles, a decision projected to preserve 800 jobs within the defence sector. - Establish a pioneering cyber command while committing £1 billion towards digital advancements. - Allocate an excess of £1.5 billion for refurbishing and updating service personnel accommodation. Sir Keir Starmer is expected to declare: "From the supply lines to the front lines, this Government is foursquare behind the men and women upholding our nation's freedom and security. "National security is the foundation of my Plan for Change, and this plan will ensure Britain is secure at home and strong abroad, while delivering a defence dividend of well-paid jobs up and down the country." The Shadow Defence Secretary, James Cartlidge, expressed scepticism regarding Labour's Strategic Defence Review promises, stating that they would be viewed with caution unless Labour could demonstrate that sufficient funding would be allocated. Labour's Shadow Defence Secretary, John Healey, had previously mentioned in an interview with The Times that there was "no doubt" the UK would achieve its goal of 3% defence spending. However, when questioned on the BBC's Sunday with Laura Kuenssberg programme, he sidestepped queries about whether the Treasury had provided any guarantees for the necessary funding. Healey also acknowledged that he did not anticipate an increase in the number of armed forces personnel until the next Parliament, citing ongoing recruitment and retention challenges. When asked about the Army's target of 73,000 personnel, he replied, "We've narrowed the gap, but we've still got more people leaving than joining. "The first job is to reverse that trend and then I want to see in the next parliament our ability to start to increase the number." In response, James Cartlidge argued, "All of Labour's Strategic Defence Review promises will be taken with a pinch of salt unless they can show there will actually be enough money to pay for them. "Whereas, far from guaranteeing the funding, John Healey has been hung out to dry by Rachel Reeves. "As recently as Thursday, Healey promised that defence spending would definitely hit 3%, but today he's completely backtracked. "These submarines are not due to enter service till the late 2030s, so how can we have any confidence Labour will actually deliver them when they can't even sustain a policy on defence spending for more than 48 hours?" Lib Dem defence spokesperson Helen Maguire commented: "This signals absolutely the right intent about the need to bolster the UK's defences in the face of Putin's imperialism and Trump's unreliability. "But this must come with a concrete commitment and detail on full funding. "Labour's mere 'ambition' rather than commitment to reach 3% of GDP on defence leaves serious questions about whether the money for these projects will actually be forthcoming. "The 2034 timeline suggests a worrying lack of urgency from the Government. "Unless Labour commits to holding cross-party talks on how to reach 3% much more rapidly than the mid-2030s, this announcement risks becoming a damp squib."

House prices rise by 0.5% month-on-month in May after April dip
House price growth accelerated in May, amid 'supportive' underlying conditions for home buyers, according to an index. Property values increased by 0.5% month-on-month in May, following a 0.6% fall in April, taking the average UK house price to £273,427, Nationwide Building Society said. The typical UK house price increased by 3.5% annually in May, compared with 3.4% in April. Robert Gardner, Nationwide's chief economist, said: 'Despite wider economic uncertainties in the global economy, underlying conditions for potential home buyers in the UK remain supportive.' A stamp duty holiday ended in March, with recent figures showing there was a stampede to get sales over the line before the deadline, followed by a transactions dip. HM Revenue and Customs (HMRC) figures published last week showed an estimated 64,680 house sales took place in April – 64% lower than the 177,440 reported in March. The study indicated the figures had been affected by changes to stamp duty rates which apply in England and Northern Ireland. Outlining underlying conditions which could be positive for home buyers, Mr Gardner said: ' Unemployment remains low, earnings are rising at a healthy pace, household balance sheets are strong and borrowing costs are likely to moderate a little if (the Bank of England base rate) is lowered further in the coming quarters as we, and most other analysts, expect.' Iain McKenzie, chief executive of the Guild of Property Professionals, said: 'After the surge in transactions earlier this year, driven by the stamp duty deadline, April's drop in sales was expected. It's likely we'll see a short period of adjustment but agent sentiment, as captured in the latest (Royal Institution of Chartered Surveyors) data, suggests optimism for the second half of the year.' Jason Tebb, president of OnTheMarket, said: 'Even though a considerable number of buyers brought forward transactions to take advantage of the stamp duty concession before it ended in March, there is still plenty of activity in the market now the incentive is no longer available.' He added: 'Lenders have been trimming mortgage rates and easing criteria in recent weeks which should help a little, giving buyers who rely on mortgages more wiggle room.' Alice Haine, a personal finance analyst at Bestinvest by Evelyn Partners, said: 'The traditional surge in listings at this time of year is a positive buyers can take advantage of, as a wider stock of homes to choose from raises the potential for heavier negotiation on price.' Tom Bill, head of UK residential research at Knight Frank said: 'There are tentative signs of momentum in the UK housing market after a slump in activity in April caused by higher rates of stamp duty but a dramatic rebound in prices doesn't feel likely. 'Concerns around inflation and the Government's financial headroom mean mortgage rates don't feel poised to drop meaningfully. Buyers also have a lot of properties to choose from this spring, which we expect to keep downwards pressure on prices in the short term.' David Johnson, managing director of property consultancy Inhous, said: 'Buyer demand picked up immediately after the bank holidays and has remained strong throughout May.' Karen Noye, mortgage expert at wealth manager Quilter said: 'Mortgage rates continue to improve meaning more buyers are finding the confidence to enter the market. 'Although lenders have started to reduce rates, many borrowers are still facing higher monthly costs than they would have a couple of years ago, particularly those coming off ultra-low fixed deals. Affordability stress testing also remains a barrier, with lenders continuing to apply caution particularly for those with smaller deposits or variable income. 'Some existing borrowers are resorting to term extensions or interest-only arrangements to ease the pressure on monthly budgets, but these are not long-term fixes and often result in higher overall repayment costs. 'The underlying issue is that property prices remain significantly out of line with average earnings, particularly in southern England, and that mismatch is limiting how far the market can stretch. 'Looking ahead, if interest rates fall further, we may see further house price increases, but with ongoing economic uncertainty, many would-be movers may decide to hold off until the outlook becomes clearer. The market is still navigating a complex landscape.'

Indivior to delist from London Stock Exchange, maintain Nasdaq listing
June 2 (Reuters) - Pharma firm Indivior (INDV.L), opens new tab said on Monday it will cancel its secondary listing on the London Stock Exchange, effective July 25, maintaining its primary listing on the Nasdaq to reduce costs and better align with its U.S.-centric business. The company, known for its opioid addiction treatment, joins a growing number of companies delisting from London, as lower valuations and weak investor appetite continue to drive firms toward U.S. markets. Shares of Indivior, which floated in London in late 2014, have dropped more than 60% from record highs hit in June 2018. The company said over 80% of its revenue now comes from the U.S., with the Nasdaq (NDAQ.O), opens new tab accounting for about 75% of recent trading volumes. The delisting aims to streamline operations and reflect the company's strategic focus on the U.S. market, it said. Indivior moved its primary listing to the United States last year. The decision to delist from London comes just months after Indivior overhauled its management. Earlier this year, it appointed David Wheadon as chair and Joe Ciaffoni as CEO.
