What are Starstreak 'laser riding' missiles and how could they help Ukraine?

Live updates: follow the latest news on Russia-Ukraine

The UK is considering sending Starstreak anti-aircraft missiles to Ukrainian forces trying to fend off the Russian attack.

“We believe that this system will remain within the definition of defensive weapons but will allow the defending force to better defend the skies,” UK Defence Minister Ben Wallace said on Wednesday.

What are Starstreak missiles?

The missiles use a guidance system that could give them an edge over older anti-aircraft missiles that use infrared seeking technology.

The offer of the portable, short-range weapon is seen as significant, because it relies on a laser beam riding guidance system.

Most short-range anti-aircraft missiles are "heat-seeking" and can be sent off course by magnesium flares dropped by aircraft as a defence, although some modern heat-seeking systems can differentiate between engine heat and flare heat sources.

Ukraine has already received around 1,000 Stingers from the US, Germany and the Netherlands ― both systems are man-portable air defence systems, or Manpads.

How do Starstreak missiles compare to Singers?

The Starstreak is also incredibly fast, reaching a maximum velocity of three times the speed of sound, or Mach 3. That’s faster than the top speed of a Stinger anti-aircraft missile, which can travel at Mach 2.5.

Both of those systems are slightly faster than the top speed at altitude of common Russian multirole jets such as the SU-35, although if the jets fly at medium altitude, they would be out of range of Manpads.

How could Starstreak missiles help Ukraine?

That might not be an option for Russian jets, however, because Ukraine still has functioning medium-range air defence systems.

That means one option for Russian jets is to fly low and fast — beyond the line of sight of medium-range systems — but that leaves them in danger of Manpads, which are optimised for fast, short-range encounters.

Starstreak missiles would be deadly for Russian helicopter pilots who, flying aircraft much slower than jets, would have little time to react in the event of a launch.

Key figures in the life of the fort

Sheikh Dhiyab bin Isa (ruled 1761-1793) Built Qasr Al Hosn as a watchtower to guard over the only freshwater well on Abu Dhabi island.

Sheikh Shakhbut bin Dhiyab (ruled 1793-1816) Expanded the tower into a small fort and transferred his ruling place of residence from Liwa Oasis to the fort on the island.

Sheikh Tahnoon bin Shakhbut (ruled 1818-1833) Expanded Qasr Al Hosn further as Abu Dhabi grew from a small village of palm huts to a town of more than 5,000 inhabitants.

Sheikh Khalifa bin Shakhbut (ruled 1833-1845) Repaired and fortified the fort.

Sheikh Saeed bin Tahnoon (ruled 1845-1855) Turned Qasr Al Hosn into a strong two-storied structure.

Sheikh Zayed bin Khalifa (ruled 1855-1909) Expanded Qasr Al Hosn further to reflect the emirate's increasing prominence.

Sheikh Shakhbut bin Sultan (ruled 1928-1966) Renovated and enlarged Qasr Al Hosn, adding a decorative arch and two new villas.

Sheikh Zayed bin Sultan (ruled 1966-2004) Moved the royal residence to Al Manhal palace and kept his diwan at Qasr Al Hosn.

The more serious side of specialty coffee

While the taste of beans and freshness of roast is paramount to the specialty coffee scene, so is sustainability and workers’ rights.

The bulk of genuine specialty coffee companies aim to improve on these elements in every stage of production via direct relationships with farmers. For instance, Mokha 1450 on Al Wasl Road strives to work predominantly with women-owned and -operated coffee organisations, including female farmers in the Sabree mountains of Yemen.

Because, as the boutique’s owner, Garfield Kerr, points out: “women represent over 90 per cent of the coffee value chain, but are woefully underrepresented in less than 10 per cent of ownership and management throughout the global coffee industry.”

One of the UAE’s largest suppliers of green (meaning not-yet-roasted) beans, Raw Coffee, is a founding member of the Partnership of Gender Equity, which aims to empower female coffee farmers and harvesters.

Also, globally, many companies have found the perfect way to recycle old coffee grounds: they create the perfect fertile soil in which to grow mushrooms.

Red flags

Promises of high, fixed or 'guaranteed' returns.
Unregulated structured products or complex investments often used to bypass traditional safeguards.
Lack of clear information, vague language, no access to audited financials.
Overseas companies targeting investors in other jurisdictions - this can make legal recovery difficult.
Hard-selling tactics - creating urgency, offering 'exclusive' deals.
