The Red Sea & the Houthis. A Geollect Spotlight
What is happening in the Red Sea?
Since the outbreak of conflict in Israel and Gaza, commercial shipping travelling through the Red Sea and the Bab al-Mandab Strait has come under attack from the Houthi group, a relatively sophisticated non-state actor operating in Yemen with heavy links to Iran. The Houthis have often claimed that these targets are linked to Israel, Israeli companies and/or Israeli individuals, and are targeting them in response to Israel's ongoing campaign against Hamas in Gaza. However, as the frequency of attacks has increased over the past few weeks, the attacks have evidently become less discriminate in their nature, suggesting that the Houthi's intent is to make the Bab al-Mandab strait unpassable for international trade.

What impact is this having on shipping and why is this significant?
Already, major shipping companies such as Hapag Lloyd and MSC & Maersk have ceased operations through the Red Sea, followed closely by British Petroleum (BP), forcing re-routing to European destinations via the Cape of Good Hope, a significantly longer route.
As well as greater cost in terms of travel and delays to supply chains, this is already having an impact on the cost of insurance too. Reuters reported that the War Risk Premium for the Red Sea area has increased ten fold, from 0.07% of the total vessel & cargo value to 0.7% over just one month. Given that much of the cargo that passes through the Red Sea is oil product tankers - a fully laden vessel being worth hundreds of millions of dollars - this has made the cost of shipping extremely expensive in a very short period of time.
Re-routing via the Gulf of Guinea - one threat for another?
Not only does re-routing critical maritime traffic significantly increase the time and cost of trade and transit, it also exposes vessels to other security threats, which may simply trade one risk for another. Any shipping heading on a course from the Cape of Good Hope toward the Mediterranean or North Sea will likely pass through the Gulf of Guinea, a littoral area which has persistently seen the highest levels of maritime piracy in the world since the decline of the the threat of Somalian piracy in the late 2000s/early 2010s. The below Storymap created by Geollect earlier this year summarises why maritime insecurity in the Gulf of Guinea will persist and remain a critical security threat to both the region and global trade for the foreseeable future.
The Houthis and Yemen
The Houthi Group
The Houthi movement is a political and military organisation formed in the 1990s. They have been fighting as a primary belligerent in the Yemeni civil war since 2014. They hold Sana’a, the country’s de jure capital, and are fighting against the internationally recognised government of Yemen as well as the Saudi led intervention force. The Houthis are backed by Iran, particularly the Iranian Revolutionary Guard Corps (IRGC) - an organisation designated an international terrorist organisation by the United States and the European Union (EU). Both the Houthis and the Iranian government follow Shia Islam, adding a pronounced sectarian lens to their conflict with their Sunni neighbours and regional powers and Israel.
The Houthi movement controls a large portion of Western Yemen, which is the most densely populated region. Estimates of their number of fighters are only approximate, but it is thought to be in the high tens of thousands.
The Houthis do not have a conventional navy – the Yemeni navy was largely destroyed at the start of the war. They are however thought to have and operate a number of small (10 metre long) boats which act as a coastguard in combination with ground-based missile systems.
During the start of the civil war, Yemen’s Air Force largely remained loyal to the internationally recognised government meaning the Houthis also lack a conventional air fighting force. They make up for this with a fleet of drones, such as the Sammad and Qasef drones. The Qasef is derivative of an Iranian design. The Sammad is claimed to be domestically produced in Houthi controlled Yemen. However, experts dispute this, claiming it has Iranian origins. The Houthis are heavily reliant on aid in terms of military equipment, training and advisors from Iran's IRGC, which heavily incentivises them to act as an Iranian proxy.
Why are the Houthis targeting shipping?
It is highly likely that the primary objective of the Houthis is to win further favour and support - both political and material - from Iran. Iran almost certainly provides the Houthis with advanced missile and drone technology, as well as regular arms, ammunition, training and support. As such, the Houthi Group align closely with Iran's geopolitical objectives. Israel and Iran are fierce regional enemies, with Israel frequently targeting Iranian supported militia groups in Syria, Lebanon and Gaza, as well as being heavily linked to targeted strikes and close quarter assassinations of key figures of Iran's nuclear programme, amongst other incidents.
Iran's other regional adversary is Saudi Arabia, who are investing heavily in their own military capability and are aligned closely with the United States and the West. However, the Houthis have been in direct conflict with Saudi Arabia since the Saudi led coalition intervened in 2014. By targeting shipping in the Red Sea and the Bab al-Mandab strait, it is highly likely that the Houthis hope to make the southern gateway to the Suez Canal unviable, thus severely affecting the flow of oil from Saudi Arabia to western markets.
The Houthis are close allies of Iran and have proclaimed their support of Hamas in its conflict with Israel. Iran has a vested interest in the conflict in the Gaza strip. However, the country has few methods available to directly support Hamas and their associated groups. It is claimed by the US that they are therefore using the Houthis as plausible deniability to perform attacks on Israeli associated commercial shipping. Houthi spokespeople state the goal of these attacks is to stand in solidarity against Israeli oppression, although this is likely a masking pretext to have a significant impact on Iran's other regional and international adversaries.
What is the threat?
The Houthi group are a textbook example of a non-state actor which uses 'asymmetric warfare' as its modus operandi. In short, it looks to capitalise on the agility afforded to it by its status as a non-state actor and exploit the weaknesses of its much more powerful adversaries by targeting international trade routes, civilian targets and lines of communication, all while using a combination of basic technology, tactics and dispersing force rather than concentrating it. While they possess missiles and drones, they cannot compete in terms of quality, mass and integrated capability with a US Carrier Strike Group.
Of note, the Houthi group will not act bound by international law, human rights or to protect civilian life and targets unless they feel it is within their interest, unlike a state actor, who face significantly greater scrutiny and consequence if they break international law. Therefore, the Houthis will look to continue to target civilian, commercial maritime traffic through the Red Sea using relatively limited force as a means of having a disproptionately high tactical, operational and strategic impact against their (and Iran's) adversaries.

What Remote Piloted Air Systems (RPAS)/Drones do the Houthis possess?
The below list demonstrates some of the capabilities of the Houthi's RPAS systems.
What is the range of each of the various systems the Houthis possess?
Interact with the below map and toggle layers on and off in the top right to compare the different ranges of the Houthi's capabilities.
Where are the Houthis launching their missiles and drones from?
As an asymmetric actor, it is unlikely that the Houthis will have any permanet launch locations established, for fear of being targeted by regional or international air power. Therefore, it is likely that the Houthis will have their missile and drone stocks stored near to natural launching areas, such as a high ground, ready to be fired at relatively short notice.
One such possible area that is a realistic possibility of being a point of origin for such launches is the Al-Hafa military camp on the south eastern boundary of the capital, Saana, as this has been previously identified by the Saudi coalition as a launch site.
Operation Prosperity Guardian
On the 18th December 2023, the United States Secretary for Defece, Lloyd J. Austin announced the establishment of Operation Prosperity Guardian (OPG). Operation Prosperity Guardian is a multinational security initiative under the remit of the Combined Maritime Forces and the leadership of the United States Navy Task Force 153, which focuses on security within the Red Sea. The countries involved in the operation are as follows, the United States, United Kingdom, Bahrain, Canada, France, Italy, Netherlands, Norway, Seychelles and Spain. A further 10 nations have reportedly joined the coalition but did want to officially announce the decision.
The stated goal of Operation Prosperity Guardian is to jointly address security challenges in the southern Red Sea and the Gulf of Aden, ensuring freedom of navigation for all countries and bolstering regional security and prosperity. While a full list of vessels involved in the operation has not been released, defence ministers from some of the involved nations have announced specific vessels which will be participating in the effort.
UK
The UK Defence Minister Grant Shapp stated that the Type-45 Destroyer HMS DIAMOND will join OPG. HMS DIAMOND is already in the Red Sea and has intercepted Houthi drones in recent weeks.
Italy
After a conference between Lloyd J. Austin and the Italian Defence Minister Guido Crosetto, Italy agreed to provide the Bergamini/FREMM class frigate VIRGINO FASAN. The ship was scheduled to begin patrolling the Red Sea as part of the European anti-piracy Atlanta operation in February 2023, but is now expected to transit the Suez Canal on the 24th December.
USA
In recent days the Pentagon moved the DWIGHT D. EISENHOWER Carrier Strike Group from the Persian Gulf into the Gulf of Aden off the coast of Yemen to support a potential US response to the ongoing maritime incidents. The Carrier Strike Group is comprised of the flagship aircraft carrier USS DWIGHT D. EISENHOWER, guided-missile cruiser USS PHILLIPINE SEA, guided-missile destroyers USS MASON and USS GRAVELY. Onboard the DWIGHT D. EISENHOWER is the 22 Carrier Air Wing with nine squadrons, as well as the Information Warfare Commander.
What's next?
It is likely that the warships involved in Operation Prosperity Guardian will use up to lethal force if necessary to defeat the Houthi's ability to target commercial shipping, assuming that their presence alone will not deter the Houthis from further targeting vessels in the Red Sea. This may even extend to targeting Houthi targets based in Yemen.
Such an intervention will likely make the Red Sea more permissible to navigate, but will remain a high risk area for the foreseeable future, certainly for as long as Israel's operation within Gaza continues at such high intensity. While the presence of an international maritime task force will lead to a likely decrease of commercial vessels being targeted, it is unlikely that it will prevent this from happening altogether. If the Houthis continue to intend to target vessels in the Red Sea, it is highly likely they will use their asymmetric advantage to find novel ways to do so, such as increasing the use of amphibious operations against selected targets.
