Military Finances Redesign of B-1 Bomber's External Pylons, Pursuing Enhanced Weapon Capacity and Hypersonic Trials
**Headline:** U.S. Air Force Boosts B-1B Bomber's Weapons Capacity with New External Pylons
The U.S. Air Force is set to enhance the B-1B Lancer's combat capabilities significantly, thanks to the External Heavy-Stores Pylon program and the Load Adaptable Modular (LAM) pylon initiative. This ambitious project aims to increase the B-1B's weapons carrying capacity by up to 50%, enabling it to carry larger and heavier payloads, including 5,000-pound-plus class munitions [1][2][3].
At the heart of this transformation are six new external pylons, each capable of carrying either two 2,000-pound-class weapons or a single weapon exceeding 5,000 pounds [2][3]. This upgrade not only expands the bomber’s missile loadout but also paves the way for testing and carrying hypersonic weapons, a critical component of modern long-range strike capabilities [1][2][3].
The addition of these pylons is partly aimed at mitigating transition risk by enhancing the B-1B’s combat capability before the B-21 Raider bomber fully enters service [1]. The B-21 Raider, a stealthy next-generation bomber currently in low-rate production, is expected to enter service within a few years, with at least 100 aircraft planned [4].
The B-1B's enhanced loadout through the LAM pylons is designed to maintain robust bomber capabilities and fill capability gaps during the transition period from the B-1B to the B-21 [1][4]. This approach helps ensure continuous global strike power in the near term while the Air Force phases in the technologically advanced B-21 in the 2030s [4].
In addition to the B-1B, the Air Force is also developing at least two air-launched hypersonic missiles, including the Hypersonic Attack Cruise Missile (HACM), which is small enough to be launched from fighters [1]. The goal is to increase the volume of fires off the B-1B in the near term.
The LAM continues in testing under the 412th Test Wing at Edwards Air Force Base, Calif., and has already demonstrated the pylon with inert munitions [3]. Boeing has revealed the Load Adaptable Modular pylon, which could allow the B-1 to carry additional weapons on external stations [2]. The system was developed under independent research and development, and it saved over two years of development time, speeding increased combat capability to the flight line.
For fiscal 2026, the Air Force plans to conduct computational fluid dynamics and wind tunnel testing of various external pylon/weapon configurations [2]. Procurement of the latest version of the Long Range Anti-Ship Missile (LRASM) will start near the end of fiscal 2027 and continue until the missile inventory objective is met [2]. With the new pylons, the B-1's loadout of JASSM or LRASM could increase from 24 missiles internally to 36 in a mix of internal and external hardpoints.
In conclusion, the External Heavy-Stores Pylon program and Load Adaptable Modular pylons significantly increase the B-1B’s weapons carrying capacity, including enabling hypersonic weapon carriage and testing. These upgrades extend the operational relevance of the B-1B, ensuring it remains a potent asset during the Air Force’s gradual transition to the B-21 Raider bomber [1][2][3][4].

- The Air Force is also developing at least two air-launched hypersonic missiles, including the Hypersonic Attack Cruise Missile (HACM), which is small enough to be launched from fighters, with the goal of increasing the volume of fires off the B-1B in the near term.
- For sports enthusiasts, it's also worth mentioning that the increased payload capacity of the B-1B could potentially open up opportunities for strategic airlift missions, such as transporting high-value goods or even airlifting equipment for major sports events around the globe.
