Eight sites between 90 and 130 metres. A 7th century BC Phoenician wreck. Two British submarines lost during WWII. A Polish destroyer. Aircraft at extreme depth. CCR or XR Hypoxic Trimix certification required for all sites on this page. Very few of these have been formally surveyed.
From US Navy aircraft at 96m to a 7th century BC Phoenician merchant vessel at 110m. Contact diveshack before planning any dive on this page.
US Navy attack aircraft at 96m off Malta. The AD/A-1 Skyraider entered service after WWII and served in Korea and Vietnam. Malta's example is one of the most intact aircraft at this depth range in the Mediterranean.
Polish destroyer at 98-100m. Hit a mine off Grand Harbour on 16 June 1942 while escorting Convoy MW11 (Operation Harpoon). The wreck sits largely intact at depth. One of Malta's most historically significant deep wrecks.
WWII German dive bomber at 100m+. The Junkers Ju-87 was used extensively in the siege of Malta. This example sits at extreme tec depth and has very rarely been dived. Advanced deco planning required.
WWII German multi-role aircraft at 106m. The Ju-88 was one of the Luftwaffe's most versatile aircraft of the Malta campaign. This southern example sits significantly deeper than JU-88 North and requires XR Hypoxic Trimix 100.
Unknown wreck at 105m+. The identity of this wreck has not been formally confirmed. The site is rarely dived. Extreme depth, CCR or XR Trimix 100 required. Contact us to discuss this dive as part of a dedicated deep tec trip.
7th century BC Phoenician merchant vessel at 105-110m, southwest of Gozo outside Xlendi Bay. Approximately 2,700 years old. Discovered by sonar survey in 2007, managed by Heritage Malta (UCHU). Cargo of amphorae and grinding stones lies in situ on the seabed. One of the deepest ancient wrecks accessible by technical divers anywhere in the world. Diving is rarely permitted and requires Heritage Malta authorisation.
British U-class submarine lost on 27 April 1942 with all 38 crew aboard. HMS Urge had torpedoed the Italian liner SS Conte Rosso and the cruiser RN Trento before her loss. The wreck was located in 2019 at 112-130m. A war grave, protected under Maltese and international law. Diving requires special authorisation.
British O-class minelaying submarine at 115-130m. Lost on 8 May 1942 after hitting a mine, with the loss of 89 lives, the largest single-incident loss the Royal Navy suffered in the Mediterranean. A war grave protected by law. Rarely dived. Requires CCR and advance authorisation.
diveshack runs the complete SSI XR pathway through XR Hypoxic Trimix 100. Our instructors operate on CCR and trimix equipment. The sites on this page are not theoretical. We have dived here.
Deep CCR dives at 100m+ are not day-trip dives. Gas planning, surface support, decompression scheduling, and weather windows require expedition-level preparation. diveshack organises dedicated deep trips with full surface backup.
HMS Urge, HMS Olympus, and the Phoenician Wreck are protected sites requiring authorisation before diving. diveshack is Malta-based and works within the Heritage Malta regulatory framework. We handle the authorisation process.
All sites on this page require either XR Hypoxic Trimix (80m sites from XR Hypoxic Trimix 80, 100m+ sites from XR Hypoxic Trimix 100) or CCR certification to the equivalent depth. Open-circuit technical divers require a minimum of XR Hypoxic Trimix 80 for the Douglas Skyraider and ORP Kujawiak. Sites at 106m and below require XR Hypoxic Trimix 100 or CCR. Contact diveshack with your current certifications before planning a trip.
Both HMS Urge and HMS Olympus are designated war graves, protected under Maltese law and the Protection of Wrecks Act. Diving these sites requires advance authorisation from Heritage Malta and, in the case of HMS Urge, the UK Ministry of Defence. diveshack can advise on the authorisation process. Unauthorised diving on war graves is a criminal offence in Malta.
The Phoenician Wreck is believed to be a 7th century BC merchant vessel discovered by sonar survey in 2007 by Malta's Heritage Malta authority. It sits at 105-110m southwest of Gozo outside Xlendi Bay at GPS coordinates 36°01'34"N 014°12'29"E. The cargo of amphorae and grinding stones remains in situ on the seabed. It is managed as an underwater cultural heritage site (UCHU) by Heritage Malta. Diving requires Heritage Malta authorisation. It is one of the deepest ancient wrecks accessible to technical divers anywhere in the Mediterranean.
Deep CCR dives at diveshack are organised as dedicated trips rather than day trips. A pre-dive planning session covers gas mixes, decompression schedules, site briefing, and emergency procedures. Surface support with oxygen and a trained rescue diver is standard. Weather windows are assessed 24-48 hours in advance. Group sizes for 100m+ dives are a maximum of two to three divers plus the guide.
Yes. Several deep sites are located near shallower recreational wrecks and reefs. A dedicated Malta tec trip typically combines deep CCR dives in the morning (when conditions are calmest) with recreational or advanced dives in the afternoon. diveshack can schedule multi-level itineraries across all depth zones.
Most visitors doing 100m+ dives spend a minimum of 5-7 days in Malta to allow for weather flexibility and gas sourcing. diveshack coordinates helium and trimix fills, equipment logistics, and boat schedules. Accommodation in Sliema is close to the boat departure point. See our Tec Dive package for guided deep site options. Contact us well in advance (ideally 4-6 weeks) so we can arrange authorisations, gas, and boat availability.
Message us on WhatsApp with your current XR or CCR certifications, your logbook count, and when you're planning to visit Malta. We'll tell you exactly what's achievable and what preparation is required.
