By 2000, the need for additional An-225 capacity had become apparent, so the decision was made in September 2006 to complete the second An-225. The second airframe was scheduled for completion around 2008,<ref>[http://www.aviationexplorer.com/Antonov_AN-225.html Antonov An-225 Mriya Aircraft History, Facts and Pictures]. Aviationexplorer</ref> then delayed. By August 2009, the aircraft had not been completed and work had been abandoned.<ref name="An-225 emerges">[http://www.flightglobal.com/articles/2009/08/17/331063/video-worlds-largest-aircraft-an-225-emerges-to-set-new-lift-record.html "World's largest aircraft, An-225, emerges to set new lift record"].

Based on Antonov's earlier [[Antonov An-124|An-124]], the An-225 has fuselage barrel extensions added fore and aft of the wings, which received root extensions to increase span. Two more [[Ivchenko Progress D-18T]] [[turbofan engine]]s were added to the new wing roots, bringing the total to six, and an increased-capacity [[landing gear]] system with 32 wheels was designed, some of which are steerable to turn the aircraft within a 60m wide runway. The landing gear allows the An-225 to [[Kneeling|kneel]] so cargo is easier to load and unload.<ref name="ramAn225"/> The An-124’s rear cargo door and ramp were removed to save weight, and the [[empennage]] was changed from a single [[vertical stabilizer]] to a [[twin tail]] with an oversized [[Stabilizer (aircraft)|horizontal stabilizer]]. The twin tail was essential to enable the plane to carry large, heavy external loads that would disturb the [[aerodynamics]] of a conventional tail. Unlike the An-124, the An-225 was not intended for [[tactical airlift]]ing and is not designed for [[STOL|short-field operation]].<ref name="goebel"/>

 

 

Initially the 225 had a maximum gross weight of {{convert|600|t|lb|abbr=on}} but the aircraft was modified in 2000–01, at a cost of US$20M, with a reinforced floor that increased the maximum gross weight to {{convert|640|t|lb|abbr=on}}.<ref name="Forward">Forward, David C: ''Antonov's Dream Machine'', p. 23.

As the Soviet space program was in its last years, the An-225 was employed as the prime method of transporting the [[Buran Shuttle]].<ref name="avzone">{{cite web |url=http://www.theaviationzone.com/factsheets/an225.asp |title=Antonov An-225 Mryia (Cossack) |work=The Aviation Zone}}</ref>{{Better source|date=May 2012|semi-valid ref}}

The An-225 has since become the workhorse of the Antonov Airlines fleet, transporting objects once thought impossible to move by air, such as locomotives and 150-ton generators. It has become an asset to international relief organizations for its ability to quickly transport huge quantities of emergency supplies during disaster relief operations.<ref name="aircraft info">{{cite web |url=http://www.aircraft-info.net/aircraft/jet_aircraft/antonov/AN-225 |work=Aircraft-Info.net |title=Antonov An-225 |accessdate=15 February 2004 |archiveurl = http://web.archive.org/web/20040401135622/http://www.aircraft-info.net/aircraft/jet_aircraft/antonov/AN-225 |archivedate = 1 April 2004}}</ref>

 

The An-225 has been contracted by the Canadian and U.S. governments to transport military supplies to the Middle East in support of Coalition forces.<ref name="aircraft info"/> In November 2004, [[Fédération Aéronautique Internationale|FAI]] placed the An-225 in the [[Guinness Book of Records]] for its 240 records. An example of the cost of shipping cargo by An-225 was over 2 million [[Danish krone|DKK]] (approx. €266,000) for flying a chimney duct from [[Denmark]] to [[Kazakhstan]] in 2008.<ref name="steelcon">[http://www.steelcon.com/fileadmin/user_upload/pdf/News/Steelcon__News_GB.pdf Steelcon News]. steelcon.com.

On 11 August 2009, the heaviest single cargo item ever sent via air freight was loaded onto the Antonov 225. At {{convert|16.23|m|ft}} long and {{convert|4.27|m|ft}} wide, the consignment–a generator for a gas power plant in [[Armenia]] and its loading frame–weighed in at a record {{convert|189|t|lb}}.<ref name = "Armenia1">[http://www.aircargonews.com/091110/FT091113.html Cargo manifest picture] ''Air Cargo News'' 13 November 2009.
