more importantly wots the endurance time ......
Broadly comparable but possibly still less than P-3C Orion, I would think considering the following ferry ranges (i.e. one-way range, typically on max fuel, not necessarily max load):
Antonov AN-10 transport: 4,075km
Antonov AN-12 transport: 5,700km (3,600km w max load)
Shaanxi Y-8 transport: 5,250-5,615km depending on source (variant?)
Shaanxi Y-9 transport: 7,800km
In 2001 and 2002, consulting between Antonov and Shaanxi resulted in modernized redesigns of the Y-8's wing and fuselage. As a consequence the Y-8's fuel capacity was increased by 50 percent. The new Y-9, originally known as the Y-8X, is basically a stretched version of the Y-8F-200. It likely has the aforementioned larger fuel capacity and hence a longer range that is said to be comparable to Lockheed C-130J
(note: given ambiguities about the Y-8 range, it may not be automatic that 50% more fuel translates to 50% more range. Y-8 ranges found multiplied by 1.5 yield 7,875-8,423km)
Lockheed C-130J Hercules: 7,400km
Lockheed L-100 Hercules: 8,950km (civilian stretched version)
By comparison, for the Lockheed Electra/Orion/Aries/Aurora:
Lockheed L-188 Electra: 8,910 km (< payload 7,938 kg: max load range > 7,080km)
USN EP-3A/B/E ARIES: 8,800 km
USN/USCG P-3c Orion: 8,945km (= operational mission at 2494 km, plus 3 hours on station)
US NOAA WP-3D/RAAF AP-3C: 9,000km
RCAF CP-14 Aurora mpa: 9,300km
Other comparisons:
Transall C-160 tranport: 8,858km
Breguet Atlantic II mpa: 9,075km
BAE Nimrod MR1/MR2 mpa: 8,340–9,265km
IL-38 mpa: 9,500km
Tu-95 Bear: 12,550km (strategic bomber)
Tu-95MS Bear-H: 15,000km (cruise missile carrier platform based on the Tu-142 airframe)
Tu-142M3 Bear-F MPA: 6,500 km combat radius (i.e. mission/operational)
