New Royal Navy Wildcat helicopters can't transmit vital data

Crews have to land and move tactical info around via USB sticks. No, really


Britain's latest military helicopter fleet has still not had a tactical data link capability fitted, two years after the aircraft entered service.

Although the new Leonardo Wildcat helicopters have already been deployed operationally aboard Royal Navy warships, including deployments as the sole helicopter aboard frigates patrolling overseas, they do not have a tactical data link (TDL) capability allowing them to transmit data to other units.

Instead, crews must use a USB stick after landing to transfer data collected by the Wildcat's radar and camera systems to its host ship. The only other alternative, at present, is for the crew to call out contacts over the radio by voice – just as Fleet Air Arm observers did during the Second World War.

Air International magazine reported in its February issue that although Wildcat HMA2s are fitted with the Bowman secure voice radio system, the helicopters still lack the TDL capability fitted to other frontline naval and military helicopters such as the Merlin and Puma.

Lieutenant Commander Anthony Johnson of 825 Naval Air Squadron told the magazine: "At present, we have to download everything our systems produce on to some form of media and present this when we land. We cannot currently transfer this data electronically whilst airborne, so we continue to use voice communication."

The magazine commented: "An uplink is considered essential for preparation of the battlefield, analysing patterns of life and delivering a kinetic effect in a littoral situation if required" – meaning smiting Her Majesty's enemies at sea after first making sure no innocent passers-by will get caught in the crossfire.

The Wildcat is fitted with a modern radar and electro-optical sensor suite, with the Seaspray 7400E radar including air-to-air, air-to-ground and air-to-surface modes. The Wescam electro-optical system, mounted in a turret on the helicopter's nose, can capture hi-res stills and video and also includes a laser range-finding capability – such as would be used in conjunction with the TDL.

The vital data link capability was deleted in 2008 as part of a cost-cutting exercise by the Ministry of Defence. At the same time, the total number of helicopters on order was cut from 70 to 62, along with a host of other vital capabilities, in the infamous phrase "fitted for but not with".

The export version of the Wildcat is fitted with a Link 16-compatible TDL.

The Ministry of Defence insists its £178bn equipment programme will create thousands of jobs over the next few years.

The Wildcat HMA2 helicopter, built by the company formerly known as Westland, is the replacement for the venerable Lynx helicopter flown by the Royal Navy's Fleet Air Arm and the Army Air Corps. ®

  • Lonestar plans to put datacenters in the Moon's lava tubes
    How? Founder tells The Register 'Robots… lots of robots'

    Imagine a future where racks of computer servers hum quietly in darkness below the surface of the Moon.

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality. Lonestar Data Holdings has a unique mission unlike any other cloud provider: to build datacenters on the Moon backing up the world's data.

    "It's inconceivable to me that we are keeping our most precious assets, our knowledge and our data, on Earth, where we're setting off bombs and burning things," Christopher Stott, founder and CEO of Lonestar, told The Register. "We need to put our assets in place off our planet, where we can keep it safe."

  • Conti: Russian-backed rulers of Costa Rican hacktocracy?
    Also, Chinese IT admin jailed for deleting database, and the NSA promises no more backdoors

    In brief The notorious Russian-aligned Conti ransomware gang has upped the ante in its attack against Costa Rica, threatening to overthrow the government if it doesn't pay a $20 million ransom. 

    Costa Rican president Rodrigo Chaves said that the country is effectively at war with the gang, who in April infiltrated the government's computer systems, gaining a foothold in 27 agencies at various government levels. The US State Department has offered a $15 million reward leading to the capture of Conti's leaders, who it said have made more than $150 million from 1,000+ victims.

    Conti claimed this week that it has insiders in the Costa Rican government, the AP reported, warning that "We are determined to overthrow the government by means of a cyber attack, we have already shown you all the strength and power, you have introduced an emergency."

    Chinese cyberspies targeted two Russian defense institutes and possibly another research facility in Belarus, according to Check Point Research.

    The new campaign, dubbed Twisted Panda, is part of a larger, state-sponsored espionage operation that has been ongoing for several months, if not nearly a year, according to the security shop.

    In a technical analysis, the researchers detail the various malicious stages and payloads of the campaign that used sanctions-related phishing emails to attack Russian entities, which are part of the state-owned defense conglomerate Rostec Corporation.

    The US Federal Trade Commission on Thursday said it intends to take action against educational technology companies that unlawfully collect data from children using online educational services.

    In a policy statement, the agency said, "Children should not have to needlessly hand over their data and forfeit their privacy in order to do their schoolwork or participate in remote learning, especially given the wide and increasing adoption of ed tech tools."

    The agency says it will scrutinize educational service providers to ensure that they are meeting their legal obligations under COPPA, the Children's Online Privacy Protection Act.

  • Mysterious firm seeks to buy majority stake in Arm China
    Chinese joint venture's ousted CEO tries to hang on - who will get control?

    The saga surrounding Arm's joint venture in China just took another intriguing turn: a mysterious firm named Lotcap Group claims it has signed a letter of intent to buy a 51 percent stake in Arm China from existing investors in the country.

    In a Chinese-language press release posted Wednesday, Lotcap said it has formed a subsidiary, Lotcap Fund, to buy a majority stake in the joint venture. However, reporting by one newspaper suggested that the investment firm still needs the approval of one significant investor to gain 51 percent control of Arm China.

    The development comes a couple of weeks after Arm China said that its former CEO, Allen Wu, was refusing once again to step down from his position, despite the company's board voting in late April to replace Wu with two co-chief executives. SoftBank Group, which owns 49 percent of the Chinese venture, has been trying to unentangle Arm China from Wu as the Japanese tech investment giant plans for an initial public offering of the British parent company.

  • SmartNICs power the cloud, are enterprise datacenters next?
    High pricing, lack of software make smartNICs a tough sell, despite offload potential

    SmartNICs have the potential to accelerate enterprise workloads, but don't expect to see them bring hyperscale-class efficiency to most datacenters anytime soon, ZK Research's Zeus Kerravala told The Register.

    SmartNICs are widely deployed in cloud and hyperscale datacenters as a means to offload input/output (I/O) intensive network, security, and storage operations from the CPU, freeing it up to run revenue generating tenant workloads. Some more advanced chips even offload the hypervisor to further separate the infrastructure management layer from the rest of the server.

    Despite relative success in the cloud and a flurry of innovation from the still-limited vendor SmartNIC ecosystem, including Mellanox (Nvidia), Intel, Marvell, and Xilinx (AMD), Kerravala argues that the use cases for enterprise datacenters are unlikely to resemble those of the major hyperscalers, at least in the near term.
