As Western supplies of high-tech weapons flow into Ukraine in preparation for the anticipated spring offensive, Russia is also trying to bolster its arsenal.
It has resorted to trading SU-35 fighter jets to Iran in return for continued supply of Iranian Shahid 136 attack drones, and also fielded state-of-the-art missile systems for the first time.
But will these radical steps make a decisive impact on the course of the war?
The Iranian attack drones are not sophisticated, or expensive, but do enable Russiato maintain nightly pressure on Ukraine’s limited supplies of air defence missiles.
However, such missiles are more of an “irritation” to Ukraine and have limited military utility.
In contrast, Russia’s latest generation of high-tech weapons – the KILLJOY Air-Launched Hypersonic ballistic missile, described by President Vladimir Putin as “undefeatable” – appeared to offer Moscow’s forces the chance to scythe through Ukrainian defences with impunity.
Before the KILLJOY was used, the West could only speculate as to the missile’s capabilities, and thus it held considerable mystique and deterrence capability.
However, the moment it was used, the West was able to analyse its capability, its limitations and its vulnerabilities – and on 3 May, it appears the Ukrainians managed to shoot one down, with several more suffering a similar fate over the following days.

West can’t risk exposing their hand
The KILLJOY would have taken years – and billions of dollars – to develop, yet much of the value lay in its potential.
Nations invest in credible military capability to deter potential aggressors. Secret weapon programmes sow seeds of doubt in the minds of enemies, even if actual capability falls some way short of that anticipated.
As a result, the West is very careful to limit the level of combat capability deployed to avoid “exposing their hand”, and limit the potential for donated weapons to find their way onto the local black market – as is the risk in Ukraine.
Western war fighters routinely do not have access to the very latest capability in conflicts such as Afghanistan, to preserve state-of-the-art high-tech weapons for any future war of national survival.
The UK’s Storm Shadow is a very capable missile, but the technology is 25 years old, and the UK is planning a midlife upgrade in the near future.

What are Storm Shadow missiles?
Likewise, the US Patriot air defence system was first fielded in 1986, and although it has been upgraded regularly, the system deployed into Ukraine is very unlikely to be the latest generation.
However, if indeed the Patriot was damaged in a Russian attack, the damage must have been light as the Patriot appears to be back up and running again.
Holding back military capability is not a new concept. In the Second World War, the allies cracked the Enigma code, which enabled intercept of all German traffic.
However, the allies were very careful to limit exploitation of Enigma – as if Germany knew it had been compromised, this vital intelligence would be lost to the allies.
Lives were lost to maintain this most sensitive secret, and that same philosophy prevails today.
Technology provides the West an asymmetric military advantage, which must be protected.
Putin’s folly was to believe his own hype – the “undefeatable” missile has proven an expensive illusion.
At least 30 people have been killed in the Syrian city of Sweida in clashes between local military groups and tribes, according to Syria’s interior ministry.
Officials say initial figures suggest around 100 people have also been injured in the city, where the Druze faith is one of the major religious groups.
The interior ministry said its forces will directly intervene to resolve the conflict, which the Reuters news agency said involved fighting between Druze gunmen and Bedouin Sunni tribes.
It marks the latest episode of sectarian violence in Syria, where fears among minority groups have increased since Islamist-led rebels toppled President Bashar al Assad in December, installing their own government and security forces.

In March, Sky’s Stuart Ramsay described escalating violence within Syria
The violence reportedly erupted after a wave of kidnappings, including the abduction of a Druze merchant on Friday on the highway linking Damascus to Sweida.
Last April, Sunni militia clashed with armed Druze residents of Jaramana, southeast of Damascus, and fighting later spread to another district near the capital.
But this is the first time the fighting has been reported inside the city of Sweida itself, the provincial capital of the mostly Druze province.
The Syrian Observatory for Human Rights (SOHR) reports the fighting was centred in the Maqwas neighbourhood east of Sweida and villages on the western and northern outskirts of the city.
It adds that Syria’s Ministry of Defence has deployed military convoys to the area.
Western nations, including the US and UK, have been increasingly moving towards normalising relations with Syria.

Concerns among minority groups have intensified following the killing of hundreds of Alawites in March, in apparent retaliation for an earlier attack carried out by Assad loyalists.
That was the deadliest sectarian flare-up in years in Syria, where a 14-year civil war ended with Assad fleeing to Russia after his government was overthrown by rebel forces.
The city of Sweida is in southern Syria, about 24 miles (38km) north of the border with Jordan.
The man convicted of the murder of British student Meredith Kercher has been charged with sexual assault against an ex-girlfriend.
Rudy Guede, 38, was the only person who was definitively convicted of the murder of 21-year-old Ms Kercher in Perugia, Italy, back in 2007.
He will be standing trial again in November after an ex-girlfriend filed a police report in the summer of 2023 accusing Guede of mistreatment, personal injury and sexual violence.
Guede, from the Ivory Coast, was released from prison for the murder of Leeds University student Ms Kercher in 2021, after having served about 13 years of a 16-year sentence.

Since last year – when this investigation was still ongoing – Guede has been under a “special surveillance” regime, Sky News understands, meaning he was banned from having any contact with the woman behind the sexual assault allegations, including via social media, and had to inform police any time he left his city of residence, Viterbo, as ruled by a Rome court.
Guede has been serving a restraining order and fitted with an electronic ankle tag.
The Kercher murder case, in the university city of Perugia, was the subject of international attention.
Ms Kercher, a 21-year-old British exchange student, was found murdered in the flat she shared with her American roommate, Amanda Knox.
The Briton’s throat had been cut and she had been stabbed 47 times.

Ms Knox and her then-boyfriend, Raffaele Sollecito, were placed under suspicion.
Both were initially convicted of murder, but Italy’s highest court overturned their convictions, acquitting them in 2015.
The Israeli military says it missed its intended target after Gaza officials said 10 Palestinians – including six children – were killed in a strike at a water collection point.
Another 17 people were wounded in the strike on a water distribution point in Nuseirat refugee camp, said Ahmed Abu Saifan, an emergency physician at Al Awda Hospital.
The Israel Defence Forces (IDF) said it had intended to hit an Islamic Jihad militant but a “technical error with the munition” had caused the missile to fall “dozens of metres from the target”.
The IDF said the incident is under review, adding that it “works to mitigate harm to uninvolved civilians as much as possible” and “regrets any harm to uninvolved civilians”.

Officials at Al Awda Hospital said it received 10 bodies after the Israeli strike on the water collection point and six children were among the dead.
Ramadan Nassar, who lives in the area, said around 20 children and 14 adults were lined up Sunday morning to fill up water.
When the strike occurred, everyone ran and some, including those who were severely injured, fell to the ground, he said.

In total, 19 people were killed in Israeli strikes in the Gaza Strip on Sunday, local health officials said.
Two women and three children were among nine killed after an Israeli strike on a home in the central town of Zawaida, officials at Al Aqsa Martyrs Hospital said.
Israel has claimed it hit more than 150 targets in the besieged enclave in the past day.
The latest strikes come after the Israel military opened fire near an aid centre in Rafah on Saturday. The Red Cross said 31 people were killed.
The IDF has said it fired “warning shots” near the aid distribution site but it was “not aware of injured individuals” as a result.

Palestinians shot while seeking aid, says paramedic
The war in Gaza started in response to Hamas’s attack on Israel on 7 October 2023, which killed 1,200 people and saw about 250 taken hostage.
More than 58,000 Palestinians have since been killed, with more than half being women and children, according to Gaza’s health ministry, which does not distinguish between civilians and combatants in its count.
US President Donald Trump has said he is closing in on another ceasefire agreement that would see more hostages released and potentially wind down the war.
But after two days of talks this week with Israeli Prime Minister Benjamin Netanyahu, there were no signs of a breakthrough, as a new sticking point emerged over the deployment of Israeli troops during the truce.
Hamas still holds 50 hostages, with fewer than half of them believed to be alive, after most of the rest were released in ceasefire agreements or other deals.
