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.

Collins Aerospace launches Tower MicroELITE surveillance system, with San Bernardino as first airport

Collins Aerospace, an RTX business, has launched Tower MicroELITE (TME), a digital display system that improves air traffic controllers' awareness of their airspace. San Bernardino Airport is the first to deploy it, to cope with a rapid rise in operations. The airport is a federal contract tower, part of a growing group of private and contract airports with rising traffic but no certified radar displays. TME is built on Collins' FAA-certified Standard Terminal Automation Replacement System. It uses commercial off-the-shelf hardware, so airports of any size can install it, including regional airports, business aviation terminals, and heliports. The system has received Federal Aviation Administration System Design Approval as an Airborne Position Reference Tool. It can be used at eligible FAA Contract Tower airports and privately operated control facilities.

RTX cash flow jumps $1.76B, but receivable sales explain $1.5B of the gain

RTX Corporation's first-half operating cash flow rose to $5.40 billion from about $3.64 billion, but receivable sales explain much of the gain. Increased factoring contributed $1.5 billion, or about 41% of the improvement. Demand for aircraft maintenance and defence is lifting the business. Second-quarter commercial aftermarket sales at its engine unit grew 25%, and adjusted operating profit rose 22%. RTX generated about $4.19 billion in first-half free cash flow. Its annual guidance of $8.50–$8.75 billion requires roughly $4.31–$4.56 billion more in the second half. The shares trade at about 25x forward earnings, against 35x for General Electric. Analysts expect about 15% growth in 2026 adjusted earnings per share, versus about 24% for General Electric.
