What believers are saying

  • RTX raised 2026 guidance after Q2 sales reached $24.7 billion and EPS hit $1.89.
  • Raytheon's 2026 framework agreements target annual output above 1,000 Tomahawks and 500 SM-6s.
  • GTF Advantage certification and Airbus deliveries extend Pratt & Whitney's recovery into 2026.

What critics are saying

  • Pratt & Whitney's GTF powder-metal issue still drives inspections, grounded jets, and lawsuits.
  • SEC subpoenas and DOJ agreements keep Raytheon's legacy conduct under active scrutiny.
  • Persistent GTF failures or fixed-price overruns can erase cash flow and damage airline trust.

What makes RTX unique

  • RTX pairs $289 billion backlog with balanced defense and commercial aerospace exposure.
  • Raytheon wins $24.4 billion SM-6 and $22.9 billion Tomahawk production contracts.
  • Pratt & Whitney and Collins feed recurring aftermarket revenue across Airbus and military fleets.

Raytheon wins $729M counter-drone deal for US Army, Qatar and Jordan

Raytheon, an RTX business, has won $729 million in contracts to supply parts of its LIDS counter-drone system to the US Army, Qatar, and Jordan. The deal includes fixed-site and mobile configurations. LIDS, or the Low, slow, small, unmanned aircraft Integrated Defeat System, uses Raytheon's Ku-band Radio Frequency Sensor (KuRFS) and the Coyote effector. The deal marks the first international sales of both. KuRFS offers 360-degree threat detection. Coyote effectors defeat single drones and swarms. Raytheon is expanding Coyote production to meet rising global demand. Planned upgrades include faster launch times, higher speeds, and greater range at higher altitudes. "LIDS provides a proven and cost-effective layer of defense," said Tom Laliberty, president of Land and Air Defense Systems at Raytheon.

RTX's Raytheon secures $6.3B contract for SM-3 IB missile interceptors

Raytheon, an RTX business, has secured a contract worth up to $6.3 billion for the production and sustainment of Standard Missile-3 Block IB interceptors. The five-year agreement, with two optional additional years, forms part of recent landmark deals between Raytheon and the Department of War. The contract supports urgent replenishment of missile defense inventory that has been used in combat. Production will primarily take place at Raytheon facilities in Tucson, Arizona, and Huntsville, Alabama. SM-3 IB is a ship- and land-based missile defense interceptor designed to defeat short- to intermediate-range ballistic missiles. It was first deployed in combat in 2024 and remains integral to the US Navy's extended-range integrated air and missile defense systems.

RTX's Raytheon secures $24.4B contract for SM-6 interceptors

Raytheon, an RTX business, has secured a five-year contract worth up to $24.4 billion for Standard Missile-6 (SM-6) interceptors. The contract includes two additional option years. The agreement ensures a consistent supply of SM-6s for the US Navy. The missile can conduct offensive strikes and missile defense missions. Raytheon President Phil Jasper said the company is focused on meeting demand through operational investments and facility improvements. The firm has expanded its workforce, strengthened partnerships across the defence industrial base, and automated production to boost output. SM-6 is the only combat-proven weapon capable of performing anti-air warfare, anti-surface warfare, and ballistic missile defence. It can be fired from various Navy ship-based platforms and land-based launchers.

United Airlines receives first GTF Advantage-powered A321XLR from RTX's Pratt & Whitney

United Airlines has received its first Airbus A321XLR aircraft powered by Pratt & Whitney's GTF Advantage engines, marking the inaugural delivery of this enhanced engine variant. The GTF Advantage offers up to twice the operational lifespan of current GTF engines and provides 4-8% more takeoff thrust, enabling extended range capabilities. The engine features an advanced hot section design and remains fully compatible with existing GTF models, simplifying fleet operations. Pratt & Whitney, an RTX business, plans to transition its entire PW1100G-JM production line to the Advantage specification by 2028. Current GTF operators will be able to access 90-95% of the Advantage's durability improvements through a Hot Section Plus upgrade option, available from early next year during scheduled maintenance visits.

Pratt & Whitney invests $25M to expand Poland manufacturing, adding 120 jobs

RTX's Pratt & Whitney is investing $25 million to expand its manufacturing facility in Niepołomice, Poland. The site produces complex tubular assemblies for commercial and military engines. The expansion, supported by the Polish government through the Polish Investment Zone Programme, will add more than 120 jobs when it becomes operational in 2028. The facility currently manufactures precision components for multiple engine types, including the GTF engine for commercial aircraft and the F135 for F-35 fighter aircraft. This investment is part of Pratt & Whitney's $125 million commitment to Polish facilities this year, including a $100 million investment in Rzeszow. Poland represents RTX's largest investment base outside the United States, with more than 9,500 employees across its businesses in-country.
