Lavochkin La-11

The Lavochkin La-11 (NATO reporting name Fang) was an early post-World War II Soviet long-range piston-engined fighter aircraft.

Development

One of the recommendations from the government testing of Lavochkin La-130 (Lavochkin La-9 prototype) was to further develop it into a long-range escort fighter. The resultant La-134 prototype (also sometimes referred to as La-9M) featured increased fuel and oil capacity. Armament was reduced to three cannons. The prototype flew in May 1947. The second prototype, La-134D had fuel capacity increased by an additional 275 l (73 US gal) with wing and external fuel tanks. The aircraft was fitted with larger tires to accommodate the increased weight and amenities for long flights such as increased padding in the seat, armrests, and a urinal. In addition, a full radio navigation suite was installed. Not surprisingly, combat performance with a full fuel load suffered. However, as the fuel load approached that of La-9, so did the performance. The aircraft was found to be poorly suited for combat above 7,000 m (23,000 ft). The new fighter, designated La-11 entered production in 1947. By the end of production in 1951, a total of 1,182 aircraft were built.

Operational history

The first documented combat use of La-11 took place on April 8, 1950, when four Soviet pilots shot down an United States Navy Consolidated PB4Y-2 Privateer over the Baltic Sea, with all 10 of the Privateer's crew lost. Later the same year, two La-11 pilots shot down a USN Lockheed P2V Neptune over the Sea of Japan near Vladivostok; one USN crew member was killed.

From February 1950, the Soviet 106th Fighter Aviation Division moved to Shanghai to defend it against bombing by the ROCAF. The division included the 351st Fighter Regiment, equipped with the La-11. On March 7, the regiment claimed a North-American B-25 Mitchell bomber, shot down near Nanjing. On March 14, 1950, a Martin B-26 Marauder bomber was claimed in Xuzhou. On March 20, 1950, five La-11 pilots encountered a group of North American P-51 Mustangs north-west of Shanghai, although the P-51 pilots immediately retreated. On April 2, 1950, two P-51s were claimed by La-11 pilots over Shanghai. After that, MiG-15s of the Soviet 29th Fighter Regiment took over the air defence role. The ROCAF stopped bombing Shanghai that June and the Soviet units left in October 1950.

By July 1950, La-11s were flying combat air patrol missions over North Korea.

On November 30, 1951, 16 La-11 fighter pilots of the 4th Fighter Aviation Regiment, Chinese People's Volunteer Army (PVA) were escorting 9 Tu-2 PVA bombers to bomb the South Korean island of Taehwa-do, in the Pansong archipelago. They were attacked by more than 30 F-86 fighters of the United States Air Force: four Tu-2 bombers and three La-11s were shot down.

The main target of La-11 pilots during the Korean War was the Douglas A-26 Invader night bomber, although numerous skirmishes with P-51s also took place. Attempts to intercept Boeing B-29 Superfortress bombers proved fruitless. La-11 required 26 minutes to reach the B-29's cruise altitude and once there had a speed advantage of only 20 km/h (12 mph) making it easy for the B-29 to evade the attacker in a shallow dive.

On July 23, 1954, a Douglas C-54 Skymaster military transport aircraft, registration VR-HEU, operated by Cathay Pacific Airways on a civilian passenger flight en route from Bangkok to Hong Kong, was shot down by two La-11 fighters of the 85th Fighter Regiment, People's Liberation Army Air Force (PLAAF) off the coast of Hainan Island, killing 10 people in an incident that has become known as the 1954 Cathay Pacific Douglas DC-4 shootdown. Although the four-engined propeller-driven Douglas (registered VR-HEU) was a C-54 Skymaster, the incident is known as "the DC-4 shootdown" because the C-54 is the military version of the Douglas DC-4, and the aircraft was flying a commercial passenger run. Three days later, near the same location, two La-11s of the same unit were shot by 12 AD-4 Skyraiders of the US Navy.

During 1954–55, La-11 fighters of the PLAAF took part in the Battle of Yijiangshan Islands escorting the ships of the People's Liberation Army Navy and Tu-2 bombers.

    We think it is a good way to bring back the memory of aircraft, persons or events sometimes quite forgotten.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
