The P2V-2 engine was improved, the nose was shaped into a semi-ellipse, and the maximum speed was increased. Six 20mm machine guns are installed on the nose, and 1 f12.7mm double machine guns are installed on the upper and rear of the fuselage. P2V- 1 and -2 are pure maritime patrol and attack aircraft.
The P2V-3 engine was further strengthened and equipped with anti-submarine weapons. From it, 1 1 shipborne experimental P2V-3c was modified, including a simulated nuclear bomb weighing 4.55 tons. It took off from the deck of an aircraft carrier with a total weight of 33,550 kilograms and dropped a "nuclear bomb" on the way, flying 6,447 kilometers. Later P2V-3 was equipped with a search radar under the fuselage, so it became a radar patrol early warning aircraft P2V-3W. Since then, other modifications have used airborne radar as standard equipment.
P2V-4 is equipped with APS-20 radar and radio wave source detector, which is used to search for targets. With the olive-shaped auxiliary fuel tank installed at the wing tip, the maximum fuel load is increased from 12650 liters to 15920 liters, and the speed and range are improved. Starting from 1962, the U.S. military aircraft model was named in a new way, so P2V-4 was renamed P-2D. Because the first three modifications have been retired, no new models have been named.
P2V-5 is equipped with 20mm machine guns at the nose and tail, and searchlights at the front end of the right wing tip.
The most productive modification of P-2E (formerly named P2V-5F) is a standard anti-submarine aircraft with an overall improved design. Two J34-WE-34 jet engines were installed under the wing to add extra thrust at critical moments. The nose is a transparent cabin for ocean observers, and the tail is replaced by a magnetic probe. 9 crew members, output 424. There are also some sub-modifications, such as DP-2e, EP-2e and SP-2e.
The P-2f anti-submarine and mine-laying aircraft has a smaller radome and a longer nose, and its engine is R3350—36W. These include ASM-N-2 launcher of MP-2F air-to-surface missile and TP-2F crew trainer.
P-2G65438+P-2F adopts J34 jet engine produced in 0955.
The weight of LP-2J anti-submarine patrol aircraft used in polar regions has increased.
Some planes are exported to Australia, Japan, Britain, Netherlands, Portugal, Canada, Argentina, Brazil and Taiwan Province Province of China. The Japanese imitation model is called P-2J.
The total output of each modification is 850 (excluding 48 Japanese imitations).
The model used by "Black Bat Squadron" is P-2H (P2V-7 according to the old naming rules of the US Navy) electronic warfare. It is reported that the "Black Bat Squadron" uses the P-2H Air Force EB-69A, which needs further verification, because the latter has only produced seven aircraft and is equipped with the US Air Force. So all the following models are called P2V-7.
P-2H is the last batch of P-2 series, which is improved from P-2F. It is equipped with two R3350—32W engines (3500 horsepower) and two J34-WE-36 jet engines, and the front landing gear, wing tip fuel tank, canopy and instrument panel are modified. Among them, SP-2H is an enhanced anti-submarine warfare with a passenger capacity of 10, formerly known as P2V-7S.
P-2 has large fuel capacity, excellent endurance and convenient operation, which is especially suitable for low-altitude and low-speed maritime search and can keep stable flight with the help of special devices. However, due to the narrow cabin, overheating in summer and poor working conditions, it is very difficult to fly at sea for more than ten hours at a temperature above 30℃.
In order to lay down the P-2V, the air force and navy at that time paid a huge price, and several planes crashed, but in the end, the "Black Bat Squadron" in Taiwan Province Province paid a huge price for the death of more than 60 people, including many electronic experts, and finally stopped reconnaissance activities.
