How the Su-33 took the Flanker to sea

The Sukhoi Su-27 “Flanker” is one of the great fighters of the late Cold War — big, long-legged and superbly agile. But the Soviet Navy wanted one thing the land-based Flanker could not do: operate from the deck of an aircraft carrier. The answer was the Su-27K (“Korabelny,” meaning ship-borne), navalised so heavily that it earned its own NATO reporting name — Flanker-D — and eventually the service designation Su-33.

Turning a heavy land fighter into a carrier aircraft meant rebuilding it around the deck. Sukhoi added folding wings and folding tailplanes so the big jet could be packed below a crowded deck, small canard foreplanes for the lift and pitch control needed at slow approach speeds, a strengthened structure, a beefed-up twin-wheel nose leg, and an arrestor hook to catch the wires on recovery. A retractable refuelling probe extended its already long reach.

Russia’s carrier, Admiral Kuznetsov, has no steam catapults. Instead the Su-33 uses a STOBAR method — Short Take-Off But Arrested Recovery — sprinting up a 14-degree ski-jump ramp at the bow and trapping on wires when it lands. First flown in 1987 and formally adopted in 1998, the Su-33 remains in limited service today, the heaviest fighter routinely flying from a ski-jump carrier.

01Why the Su-33 exists: giving the Soviet Navy a real carrier fighter

For most of the Cold War the Soviet Navy flew short-ranged vertical-takeoff jets like the Yak-38 from its small carriers — useful for show, marginal in combat. When the larger Admiral Kuznetsov-class ship was designed with a full-length flight deck and a ski-jump, the Navy finally had room for a proper fighter. Rather than start from scratch, Sukhoi navalised its excellent Su-27, producing the Su-27K / Su-33.

The result gave the fleet, for the first time, a carrier aircraft with the range, radar and missile load of a front-line air-superiority fighter. It was never built in large numbers — only around two dozen production airframes — and it remains a niche type tied to a single ship. But as an engineering exercise it proved the heavy Flanker could be adapted to the punishing world of carrier flying.

Design & Engineering

What makes the Su-33 special

01

Navalised from nose to tail

Turning the Su-27 into the Su-33 meant far more than adding a hook. Sukhoi fitted folding wings and folding horizontal tails for deck stowage, added canard foreplanes behind the cockpit for extra lift and control at slow approach speeds, strengthened the airframe, and reinforced the landing gear with a twin-wheel nose leg. An arrestor hook and a retractable refuelling probe complete the carrier fit.

02

Ski-jump launch, no catapult

Admiral Kuznetsov has no catapults, so the Su-33 launches using a STOBAR technique: it accelerates along the deck and up a 14-degree ski-jump ramp that flings it into the air at low speed. That limits the fuel and weapons it can carry off the deck compared with a catapult launch — a real constraint of Russia’s carrier design, not of the aircraft itself.

03

A big Flanker’s reach at sea

Beneath the carrier kit, the Su-33 keeps the Flanker’s strengths: two AL-31F3 afterburning turbofans, a large internal fuel load giving roughly 3,000 km of range, a refuelling probe, and up to 12 hardpoints. For fleet air defence far from home, that combination of range, endurance and missile load is exactly what a navy wants overhead.

02The Su-33’s canards: why a carrier Flanker grew foreplanes

Landing on a carrier means flying a stable, controllable approach at low speed and thumping the deck hard enough to catch a wire. To give the heavy Flanker better behaviour in that regime, Sukhoi added canard foreplanes ahead of the wing. They increase lift and improve pitch authority at high angles of attack, letting the Su-33 fly a slower, more precise approach than the tail-only Su-27. The same foreplanes also sharpen its agility — a side benefit of a change made mainly for the deck.

03STOBAR vs catapult: the ski-jump’s hidden cost

Western supercarriers use steam or electromagnetic catapults to fling aircraft off the deck at flying speed regardless of weight. Kuznetsov instead uses a ski-jump: the Su-33 must generate its own takeoff speed along a limited deck run. That works, but it caps the weight the jet can lift off — so in practice a ski-jump-launched Su-33 often trades fuel or weapons for the performance to get airborne safely. It is one reason the type is regarded as a capable fighter tied to a limited launch system.

04The Su-33’s cost: why no firm price exists

The Su-33 was a Soviet, then Russian, state product built in tiny numbers for a single customer and never offered on an open export market. As a result there is no reliable public flyaway price or cost-per-flight-hour for the type. With only around two dozen aircraft ever built, unit costs would have been high by fighter standards simply because the development bill was spread across so few airframes — but any specific dollar figure you see attached to a Su-33 should be treated as an estimate, not a sourced number.

Timeline

From carrier prototype to combat deployment

1984

Navalisation begins

Sukhoi starts adapting the Su-27 into the carrier-capable Su-27K, with folding wings, canards and an arrestor hook.

1987

First flight

The T-10K prototype of the navalised Flanker makes its maiden flight on 17 August 1987.

1989

First carrier landing

Test pilot Viktor Pugachyov makes the first arrested landing aboard the carrier (then named Tbilisi) on 1 November 1989.

1998

Enters service

The type is formally adopted by the Russian Navy as the Su-33, equipping the Northern Fleet’s carrier air regiment.

2016

First combat

Su-33s deploy aboard Admiral Kuznetsov off Syria — the type’s combat debut — striking ground targets with bombs.

2016

A jet lost at sea

In December a Su-33 is lost on approach after an arrestor cable reportedly snapped; the pilot ejects safely.

2010s–20s

Upgrades

Surviving Su-33s receive avionics and targeting upgrades to extend their air-to-ground capability.

Today

Still flying, in small numbers

The Su-33 remains in limited Russian naval service, tied to the fortunes of a single, often-refitting carrier.

Stories & Eyewitnesses

Twelve stories about the Su-33

Origins

From land Flanker to sea Flanker

The Su-27K was the Soviet Navy’s bid to put a heavy, capable fighter on a carrier deck.

Read the full story
The Su-33 began life as the Su-27K, a navalised version of Sukhoi’s superb Su-27 air-superiority fighter. Where earlier Soviet carriers made do with short-ranged vertical-takeoff jets, the new Admiral Kuznetsov-class ship had a full flight deck and a ski-jump — room at last for a real fighter. Adapting the proven Flanker was faster and cheaper than designing a naval aircraft from a clean sheet.
Ski-jump

No catapult, so a ramp

Admiral Kuznetsov has no steam catapults, so the Su-33 sprints up a 14-degree ski-jump.

Read the full story
Unlike Western supercarriers, Kuznetsov launches its aircraft without catapults. The Su-33 accelerates along the deck and up a curved ski-jump ramp at the bow, which throws it into the air at low speed to complete its climb. It is a simpler, cheaper system than a catapult — but it limits how heavy the jet can be at launch, so pilots often trade fuel or weapons to get airborne with margin.
Canards

Foreplanes for the deck

Small canards behind the cockpit give the Su-33 the lift and control it needs on a slow approach.

Read the full story
One of the most visible differences between a Su-33 and a land-based Flanker is the pair of small canard foreplanes ahead of the wing. They add lift and improve pitch control at the high angles of attack and slow speeds of a carrier approach, letting the pilot fly a stable, precise path onto the deck. They also make the already-agile Flanker even more manoeuvrable — a welcome bonus.
Folding

A Flanker that folds

Wings and tailplanes fold so the big fighter fits below a crowded carrier deck.

Read the full story
The Su-27 is a large aircraft, and deck space on a carrier is precious. So the Su-33 gained folding outer wings and folding horizontal stabilisers, shrinking its span from 14.7 m to about 7.4 m for stowage. Folded up, the heavy fighter can be packed onto lifts and into the hangar deck alongside the rest of the air wing.
First flight · 1987

The T-10K takes off

The navalised Flanker prototype first flew on 17 August 1987.

Read the full story
Development of the carrier Flanker ran through the mid-1980s, and the T-10K prototype made its first flight on 17 August 1987. Over the following years the aircraft was refined for the unique demands of carrier flying — the approach, the trap, the ski-jump launch — before the design was frozen for production as the Su-27K, later the Su-33.
First landing · 1989

Trapping aboard for the first time

Test pilot Viktor Pugachyov made the first arrested carrier landing on 1 November 1989.

Read the full story
On 1 November 1989, Sukhoi test pilot Viktor Pugachyov flew the first-ever arrested landing of the type aboard the carrier then named Tbilisi (later Admiral Kuznetsov). It was a milestone for Soviet naval aviation — the first time a conventional high-performance fighter had trapped aboard one of their ships — and it validated the whole STOBAR approach.
Service · 1998

Officially a Su-33

The type was formally adopted by the Russian Navy in 1998.

Read the full story
The collapse of the Soviet Union slowed the programme and cut the planned buy dramatically. The aircraft was finally, formally adopted into Russian Navy service in 1998 as the Su-33, equipping the carrier air regiment of the Northern Fleet. Only around two dozen production aircraft were ever built — a fraction of what had once been envisaged.
Syria · 2016

The Flanker goes to war

The Su-33 saw its first combat during the 2016 Admiral Kuznetsov deployment off Syria.

Read the full story
In late 2016 Admiral Kuznetsov sailed to the eastern Mediterranean, and its Su-33s flew their first-ever combat missions, striking targets on the ground in Syria. Because the ski-jump limited launch weight, the jets typically carried modest bomb loads. The deployment demonstrated the capability — but also exposed the strain of operating a small carrier air wing on active operations.
Loss · 2016

A snapped arrestor cable

One Su-33 was lost on approach in December 2016 when a wire reportedly failed; the pilot ejected safely.

Read the full story
During the Syria deployment, on 3 December 2016, a Su-33 was lost while attempting to recover aboard Kuznetsov. According to the Russian account, the arrestor wire snapped, the aircraft failed to stop and went over the bow into the sea. The pilot ejected and was rescued unhurt. It came weeks after a MiG-29K was lost in a separate recovery mishap — after which some aircraft were flown ashore to operate from land.
China

The J-15 question

China’s J-15 is derived from a Su-27K prototype — but it is not a Su-33.

Read the full story
China evaluated an unfinished early Su-27K prototype (a T-10K airframe) obtained from Ukraine, and used it to help develop its own carrier fighter, the Shenyang J-15 “Flying Shark.” While the J-15 clearly draws on the Flanker layout, it uses Chinese avionics, systems and engines and is a separate aircraft — not a Su-33. Russia has publicly disputed the resemblance.
Numbers

A very small fleet

Only around two dozen production Su-33s were ever built.

Read the full story
The Su-33 is one of the rarer front-line fighters in the world. With just one carrier to fly from and a post-Soviet defence budget under pressure, Russia built only around 24 production aircraft. That small fleet, tied to a single often-refitting ship, is why the type is seen far less often than its land-based Flanker cousins.
Future

Flanker or Fulcrum at sea?

Russia selected the lighter MiG-29K as the future carrier fighter.

Read the full story
Despite the Su-33’s capability, Russia chose the smaller, more modern and multirole MiG-29K/KUB as the aircraft to carry its naval aviation forward — it takes up less deck space and has updated radar and systems. The Su-33 continues to serve alongside it in small numbers, upgraded to keep flying, but its story is now firmly that of a limited, specialised fleet.

Combat Record

A brief, single deployment

The Su-33 has fought in only one campaign. During the 2016–17 Admiral Kuznetsov deployment off Syria, its jets flew the type’s first-ever combat missions, striking ground targets. It has no confirmed air-to-air combat record. These figures are best read as a record of a small fleet on a single, difficult cruise rather than a sustained combat history — and casualty and sortie claims from that deployment should be treated with caution.

Questions & Answers

Everything people ask about the Su-33

Can I fly in a Su-33?
No — the Su-33 is a rare, front-line Russian naval fighter and there are no public rides in one anywhere. You can, however, fly in several genuine ex-military jets today — see migflug.com/flights-prices/ for the fighter-jet experiences MiGFlug actually offers.
What is the Su-33 and how is it different from the Su-27?
The Su-33 (originally Su-27K) is a navalised, carrier-capable version of the Su-27 Flanker. It adds folding wings and tailplanes, canard foreplanes, a strengthened airframe, reinforced landing gear, an arrestor hook and a refuelling probe so it can operate from the carrier Admiral Kuznetsov.
How does the Su-33 take off from a carrier without a catapult?
It uses a STOBAR method — Short Take-Off But Arrested Recovery. The jet accelerates along the deck and up a 14-degree ski-jump ramp, which launches it at low speed. It recovers by catching arrestor wires with its hook. Kuznetsov has no catapults.
Is the Su-33 the same as the Chinese J-15?
No. China used an unfinished early Su-27K prototype from Ukraine to help develop its own carrier fighter, the Shenyang J-15. The J-15 borrows the Flanker layout but uses Chinese avionics, systems and engines — it is a separate aircraft, not a Su-33.
How many Su-33s were built?
Only around 24 production aircraft. Post-Soviet budget pressure and a single carrier to fly from kept the fleet very small, which is why the type is rarely seen.
Did Russia lose a Su-33 in Syria?
Yes. During the 2016 deployment, on 3 December, a Su-33 was lost while trying to land on Admiral Kuznetsov when an arrestor cable reportedly snapped. The pilot ejected and was rescued safely. A MiG-29K had been lost in a separate recovery mishap weeks earlier.
Is the Su-33 still in service?
Yes, in small numbers. The Su-33 remains in Russian Naval Aviation service, upgraded over the years, though its activity is tied to the availability of the carrier Admiral Kuznetsov, which has spent long periods in refit.
