פריסה הראשונה צפויה עוד השנה, היעד - אוקינאווה
In the first overseas deployment of the new Poseidon – a derivative of the Boeing 787-800 airliner that is being delivered on schedule and on budget – Patrol Squadron Sixteen, or VP-16, led by Cmdr. Molly Boron, will deploy to Kadena Air Base, Okinawa, Japan, where the Navy has maintained a long-range patrol presence for many years. Poseidons are scheduled to be operational at Kadena on Dec. 1, 2013.
וזה ה "אויב"
A 1997 estimate by the U.S. Navy credits North Korea with having four former Soviet “Whiskey” class submarines, twenty-two Chinese “Romeo” class subs and a small number of locally built “Romeo” derivatives known as Sang-O class submarines. Other sources put Pyongyang’s inventory of diesel-powered submarines as high as 70. Kadena is the spot from which U.S. maritime patrol crews keep their eyes on the North Korean undersea threat, as well as other naval developments in the region.
למה בעצם מחליפים את האוריון, הסוס הותיק?
The Orion gave crews a rough ride during extended patrol duty at low altitude, often while flying with one engine shut down to extend range and loiter time. The barf bag was a standard item of equipment for perennially airsick Orion sailors. Being at wavecap altitude meant plenty of flying in a salt-spray environment, which can be corrosive to any aircraft. The average P-3C today has 17,000 hours, one has 23,000, and nearly all of that time has been “hard” time accrued under demanding flying conditions.
The P-8A can receive air-to-air refueling, a capability not found on the Orion. The P-8A carries a crew of nine compared with 11 for a P-3C.
עוד על ההבדלים בצוותים
Orions fly with a crew of eleven, but Poseidons will fly with nine, including three pilots, two NFOs, two ASW acoustic operators and two non-acoustic operators. The P-8 carries no flight engineer or inflight technician. Rather than sitting at forward-facing tactical workstations as in the P-3C, P-8 NFOs/ tactical operators sit along one “rail” on the port side of the aircraft.
The P-8A will operate in coordination with the MQ-4C Triton high-altitude unmanned aerial vehicle when the latter becomes operational in 2016.The Navy is building a new hangar at Kadena for the Poseidon, which has greater external dimensions than the P-3C.
ההבדלים בביצועים
Speed is a key difference between the two patrol airplanes, the P-3 cruising at around 300 knots and the P-8 at about 500. With each of its CFM-56-7 engines producing 27,000 pounds max thrust, the Poseidon’s climb performance far exceeds the P-3C’s.
עוד יתרונות
Newness not only brings reliability, it brings refinement. Compared with the P-3C, lower levels of vibration and noise, better cabin cooling, and a more flexible wing offering a better ride combine to significantly reduce crew fatigue. With a required 10.5 hour endurance — the same as the P-3C – the P-8A’s improved environmentals will surely improve efficiency, as will its speed. “A big difference is the broad area search capability of the P-8A,” Buck asserts. “In an ASW search, she can cover a significantly greater body of water and she carries the weapons to go through the entire kill chain. She gets to and from the on-station area much quicker because of her dash speed and her ability to climb.”
מסתבר שלפוסיידון יש גם תצוגה עילית
The VP-16 pilots with whom we spoke praised the HUD, which allows them to keep their heads above the instrument panel, particularly at low altitude. Likewise, the TCAS and radar increase situational awareness dramatically, and the autopilot reduces pilot fatigue.
זה נשמע קצת בעייתי למטוס נצ"ל וסיור
The Poseidon will spend more time at higher altitude and, even when down low, will offer a smoother ride. But a turbofan engine is less fuel-efficient than the Orion’s turboprop at low level, so P-8A operators expect to spend most of their time above 28,000 feet. Work is progressing to adapt the 12.75-inch Mark 54 lightweight torpedo – already optimized for air-to-underwater use against submarines, but typically deployed today at low level – so the P-8A can drop it from high altitude.
הפריסה הצפויה - 12 טייסות
The Navy hopes eventually to have five P-8A squadrons at Naval Air Station Jacksonville, Fla.; four at Naval Air Station Whidbey Island, Wash., and three at Marine Corps Air Station Kaneohe Bay, Hawaii. Consideration is being given to dispensing with the Kaneohe presence and consolidating all Poseidon units at Jax and Whidbey.
שימו לב שהאוריין השיאן צבר כנראה 26K שעות ולא 23K שעות כמו שנאמר בכתבה אחרת
It’s about time. At its Cold War peak the maritime patrol community boasted 24 active VP squadrons and more than 240 P-3s. Today there are half as many squadrons and approximately 85 Orions available for operations. The average P-3C has logged more than 17,000 flight hours and one aircraft – Bureau Number 158919, or “Nine Inch Nails” as it’s affectionately referred to in the fleet – has racked up more than 26,000 hours. Both numbers significantly exceed the original design life of the airframe, with much of the flight time accrued at low level.
קצב האספקה הצפוי
As of late February, the P-8 program had amassed over 6600 hours – the bulk of which have been flown by three developmental test aircraft and three operational test aircraft at NAS Patuxent River. Six LRIP Lot 1 P-8s have been delivered to NAS Jacksonville ahead of schedule. Boeing is slated to deliver seven LRIP Lot 2 aircraft in 2013. When all 117 P-8As on order are delivered by 2020, each squadron will have a complement of seven aircraft and twelve aircrews..
הלך ה MAD...
A notable omission is the magnetic anomaly detection (MAD) system and the empennage boom which gave the P-3 its characteristic stinger tail. According to Rear Adm. Buck, analysis showed that the P-8’s sensor package (including the latest Multi-Static Active Coherent sonobuoys) would be able to perform all primary mission sets without the MAD system.
אירוני מעט, אבל ההודים דווקא בחרו כן לצייד את ה P-8 שלהם ב MAD
