AIM 54 Phoenix reborn after two decades!


Sm2 from surface to air give 240km with additional booster 460km range.
In air to air launch it should give atleast 350-400km range. descent energy with descent kill probability at 350km. This is obviously against for pl21(ramjet) & pl12D (ramjet).
Wonder how would be pl15d.

Fortunately we have astra mk3 SFDR ramjet. Good progress is happening there.
We need to make a enlarged version like pl21 out of it.
 
BACKGROUND of Next-Generation Bomber
The Next-Generation Bomber (NGB; unofficially called the 2018 Bomber or B-3 Bomber) was a program to develop a new medium bomber for the United States Air Force. The NGB was initially projected to enter service around 2018 as a stealthy, subsonic, medium-range, medium payload bomber to supplement and possibly—to a limited degree—replace the U.S. Air Force's aging bomber fleet (B-52 Stratofortress and B-1 Lancer). The Long Range Strike Bomber (LRS-B) heavy bomber program superseded the NGB program.

TIMELINE of B-21 Raider Bomber :-
The Air Force intends the B-21 to replace the Rockwell B-1 Lancer and Northrop Grumman B-2 Spirit by 2040, and possibly the Boeing B-52 Stratofortress.
The Air Force began planning for the B-21 in 2011. The design goals in January 2011 were :-
- Total program cost estimated at $40 to $50 billion.
- Fleet size of 175 aircraft: 120 for ten combat squadrons, plus 55 for training and reserves.
- Subsonic maximum speed.
- Range: 5,000+ nautical miles (9,260+ km).
- "Optionally manned" (for non-nuclear missions).
- Total mission durations of 50 to 100 hours (when unmanned).
- Ability to "survive daylight raids in heavily defended enemy territory".
- Ability to carry thermonuclear weapons.
-Designed to use commercial off-the-shelf propulsion, C4ISTAR, and radar technologies.
- Intelligence, surveillance, target acquisition, and aerial reconnaissance along with command and control gear to enable the crew to direct other aircraft and forces.

Air Force issued a request for proposal to develop an LRS-B aircraft in July 2014,
awarded the major development contract in 2015.
In 2016, then–Secretary of the Air Force Deborah Lee James said that the B-21 would be a "fifth-generation global precision attack platform" with networked sensor-shoot capability. At the 2016 Air Warfare Symposium, Air Force officials announced that the LRS-B would be formally designated "B-21" because the aircraft would be the 21st century's first bomber. In March 2016, the USAF announced seven tier-one suppliers for the program: Pratt & Whitney, BAE Systems, Spirit AeroSystems, Orbital ATK, Rockwell Collins, GKN Aerospace, and Janicki Industries. In September 2016, Air Force officials announced that the B-21 would be named "Raider" in honor of the Doolittle Raiders. In 2016, the F-35 program manager Chris Bogdan said the B-21's engines would be similar enough to the F-35's Pratt & Whitney F135 engine to reduce its cost.
In January 2017, Northrop Grumman was awarded a $35.8 million contract modification for a large coatings facility at Plant 42, to be completed by the end of 2019. The contract announcement did not specifically mention B-21, but the facility was likely meant for B-21 stealth coating.
The program completed its critical design review in December 2018.
By the summer of 2019, it was reported that construction of the first aircraft was underway.
In January 2020, Air Force officials released new B-21 renderings.
In early 2021, several media outlets reported that as completion of the first B-21 approached, construction on the second unit had begun. At a congressional hearing in June 2021, Darlene Costello, the acting Assistant Secretary of the Air Force Acquisition, Technology & Logistics, confirmed that the first two B-21s were under construction at Plant 42.
By February 2022, six B-21s were under construction. About 8,000 Northrop Grumman employees had worked on the program with more than 400 suppliers from at least 40 states.
The first B-21 test aircraft was unveiled at Northrop Grumman's production facilities in Palmdale, California, on 2 December 2022. At the unveiling, Northrop CEO Kathy Warden said that the B-21 is designed with modular, open systems architecture to allow easy upgrades and, potentially, the ability to export components to foreign buyers. Warden said that the B-21's internal operations were "extremely advanced compared to the B-2" and that the B-21 was slightly smaller than the B-2, with a longer range.
The first B-21s are not prototypes but rather test aircraft that the Air Force will convert to operational configuration after the completion of tests.
In 2022, Northrop Grumman describes the B-21 as "the world's first sixth-generation aircraft."
In September 2023, program officials said fueling and engine tests were proceeding ahead of the anticipated first flight by year's end.
The B-21 made its first flight on 10 November 2023 at the Air Force's Plant 42 in Palmdale, California.
On 23 January 2024, a low rate initial production (LRIP) contract was awarded.
It is expected to enter service by 2027.
Assembly of the B-21 takes place at the United States Air Force Plant 42 near Palmdale, California, at the same facility Northrop Grumman used during the 1980s and 1990s to build B-2 bombers.

Sensetive date of US platforms leaked by a defense contractor named RTX.

[F-22, F-35, B-2 Bomber's Sensitive Data Leaked To China, Russia & Iran; US State Department Fines RTX Corp](https://www.eurasiantimes.com/f-22-f-35-b-2-bombers-sensitive-data-leaked/image/jpeg)

US State Department concluded a $200 million settlement with defense contractor RTX over charges related to mishandling military secrets, including sensitive data about the advanced F-22 and F-35 fifth-generation fighter jets and the B-2 Spirit bomber.**

These breaches occurred as RTX employees traveled to China, Russia, Iran, and other nations, raising concerns about the protection of classified information.

The settlement results from RTX’s voluntary disclosure of 750 violations of the Arms Export Control Act and International Traffic in Arms Regulations (ITAR), which occurred over six years, from August 2017 to September 2023.


According to the State Department’s statement, the violations involved unauthorized exports of defense articles due to improper jurisdiction and classification, unauthorized exports of classified defense articles, and the unauthorized transport of defense articles by employees to proscribed destinations.

“RTX disclosed all of the alleged violations voluntarily,” the State Department emphasized in its announcement, released on August 30. “RTX also cooperated with the Department’s review of this matter and has implemented numerous improvements to its compliance program since the conduct at issue.”

https://breakingdefense.com/2024/08/state-department-rtx-reach-200m-settlement-for-export-violations,
An RTX spokesperson noted “The action is in line with the company’s expectations, which we disclosed during the company’s second-quarter earnings report on July 25, 2024.”

This statement suggests that RTX had anticipated the settlement and had already begun addressing the compliance issues that led to the violations.

As part of the settlement, the State Department has agreed to suspend $100 million of the $200 million fine, provided that RTX uses these funds for remedial compliance measures approved under the Consent Agreement. These measures aim to bolster RTX’s compliance program, ensure stricter adherence to export regulations, and safeguard military secrets.

Additionally, for at least the next 24 months, RTX will employ an external Special Compliance Officer to oversee the implementation of the Consent Agreement. This will include at least one external audit of RTX’s ITAR compliance program and the adoption of further compliance measures.

**Details Of The Violations**
Colby Badhwar, a journalist with the English-language version of the Russia-focused media outlet Insider,

View: https://x.com/ColbyBadhwar/status/1829575528048902425 reported that most violations were committed by Rockwell Collins before its 2018 acquisition by Raytheon, now part of RTX.

However, the violations spanned multiple RTX divisions, highlighting systemic compliance issues across the company. The proscribed destinations involved in these breaches included Iran, Lebanon, Russia, and China, underscoring the gravity of the violations.

Many of the violations seem to stem from RTX employees traveling internationally while carrying their work laptops.

These employees attempted to access their laptops during these trips, unaware that doing so could expose sensitive information.

According to the State Department, these laptops contained a range of “defense articles” tied to critical US military programs, such as the Aegis Ballistic Missile Defense System, the B-2 Spirit bomber, the F/A-18 E/F Super Hornet, the F-35 Lightning II, and the Boeing E-3 AWACS.

B-2 Bomber: Via: Edwards AFBOne key incident occurred in May and June 2021, when an RTX employee traveled to St. Petersburg, Russia, with an RTX-issued laptop loaded with ITAR-controlled technical data related to at least five military aircraft.

During the trip, the employee noticed several cybersecurity alerts and reported them to the cybersecurity team. However, these alerts were “incorrectly dismissed” as false positives, likely due to the team’s transition to a new cybersecurity tool.

This lapse in security protocols highlights the risks associated with inadequate cybersecurity measures, especially in regions with heightened surveillance.

In another case, an RTX employee traveled to Iran and attempted to log into his computer while in the country. RTX’s security team quickly detected and froze the laptop, but further investigation revealed that its hard drive contained highly sensitive technical data on the B-2 Spirit bomber and the F-22 Raptor fighter.

The presence of such critical information in a sanctioned nation like Iran represents a severe breach of US security protocols, as this kind of data is typically heavily restricted to prevent its exposure to potential adversaries.

Another troubling incident involved an employee who made multiple trips to Lebanon. An internal RTX investigation later found that this employee’s laptop contained technical data on advanced missile systems, including the Standard Missile-3, Standard Missile-6, and ESSM missiles.

In a 2023 disclosure, RTX revealed that in January 2023, it had improperly exported technical data related to an F-22 Raptor component without authorization. This data, which had been misclassified in March 2018, was sent to two Chinese employees at Collins’ Shanghai facility.

The US government reviewed the files involved and concluded that this unauthorized export of technical data had compromised national security and negatively impacted a Department of Defense program of record.
 
As part of the decree of US President Donald Trump on strengthening the border between Mexico and the United States, the transfer of Marine Corps units on MV-22B tiltrotor aircraft has begun.
The Bell V-22 Osprey tiltrotor is a hybrid of an airplane and a helicopter, it made its first flight in 1989. The Bell V-22 tiltrotor was developed for about 30 years by Bell Helicopter and Boeing Rotorcraft Systems, several tens of billions of dollars were spent on the development, there were many scandals.
The power plant of the tiltrotor consists of two Rolls-Royce engines located in rotating nacelles at the ends of the wing. The power plant has an exhaust gas cooling system, this reduces the visibility of the aircraft in the IR range. The engines change their position from vertical to horizontal in about 12 seconds. In general, it can be said that the Bell V-22 tiltrotor is very complex, the fuel supply, engine control and other systems were optimized for a long time, this affected the reliability.
The Bell MV-22 tiltrotor is expensive and difficult to operate; when used in Afghanistan, the engine life was only 200 hours. Despite this, the US military is happy with it. The Bell CV-22B can reach a maximum speed of 565 km/h in airplane mode, 185 km/h in helicopter mode, and the flight altitude is up to 7,620 meters. The tiltrotor can carry 24 paratroopers or 12 wounded on stretchers. The weight of the cargo carried on the external sling is 6,140 kg, inside the cargo cabin - 9,000 kg, the crew is 3 people in the MV-22 or 4 in the CV-22.
